text: It has two equal sides, two equal angles, and one right angle.
text: A right triangle is a special case of a triangle where 1 angle is equal to 90 degrees.
text: There are three special names given to triangles that tell how many sides (or angles) are equal.
text: All isosceles right triangles are similar since corresponding angles in isosceles right triangles are equal.
text: An equilateral triangle has the same pattern on all 3 angles, an isosceles triangle has the same pattern on just 2 angles, and a scalene triangle has different patterns on all angles since no angles are equal.
text: The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π/2 radians, is equal to the sum of the other two angles.
text: In the right triangles ABC, DEF, if the acute angle at B is equal to the acute angle at E, then those triangles will be similar.
text: For, the three angles of the right triangle are together equal to two right angles (Theorem 9); therefore, the two acute angles together will equal one right angle.
text: Note that since the right triangle is isosceles, then the angles at the base are equal.
text: The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.
text: Angles of every equilateral triangle are equal to 60°
text: A right angle is equal to 90 degrees.
text: If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.
text: Book 1 Postulate 4 states that all right angles are equal, which allows Euclid to use a right angle as a unit to measure other angles with.
text: The two right angled triangles have the right angles and angles ACB and DFE equal, therefore the third angles are also equal.
text: Right angle triangle: When the angle between any two sides is equal to 90 degrees it is called as right angle triangle.
text: If one of the angles is 90° and the other two angles are equal to 45 0 each, then the triangle is called an Isosceles Right Angled Triangle, where the adjacent sides to 90° are equal in length to each other.
text: This means that the angles will also be equal —
text: Right-angled triangle - A right-angled triangle is a triangle that has an angle that is equal to 90 degrees.
text: - A right-angled triangle is a triangle that has an angle that is equal to 90 degrees.
text: Remember that if the sides of a triangle are equal, the angles opposite the side are equal as well.
text: The angles that are opposite the equal sides are also equal.
text: In this type of triangle, the angles are also equal, so it can also be called an equiangular triangle.
text: If the other two angles are equal, that is 45 degrees each, the triangle is called an isosceles right angled triangle.
text: Mathematicians would say that the blue and the red triangles are similar triangles; the angles are equal, but the size is different.
text: If all the angles are equal, and they add up to 180, then it has to be 60 degrees!
