<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.

<H1>Parallelism</H1>
<p>
There are four points: $A(x_1, y_1)$, $B(x_2, y_2)$, $C(x_3, y_3)$, and $D(x_4, y_4)$. Write a program which determines whether the line $AB$ and the line $CD$ are parallel. If those two lines are parallel, your program should prints "<span>YES</span>" and if not prints "<span>NO</span>".
</p>
<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.

<H2>Input</H2>
<p>
Input consists of several datasets. In the first line, you are given the number of datasets $n$ ($n \leq 100$). There will be $n$ lines where each line correspondgs to each dataset. Each dataset consists of eight real numbers:<br/>
<br/>
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$ $x_4$ $y_4$<br/>
</p>
<p>
You can assume that $-100 \leq x_1, y_1, x_2, y_2, x_3, y_3, x_4, y_4 \leq 100$.
Each value is a real number with at most 5 digits after the decimal point.
</p>
<H2>Output</H2>
<p>
For each dataset, print "<span>YES</span>" or "<span>NO</span>" in a line.
