Question: A triangle has side lengths of 7 cm, 24 cm, and 25 cm. A student claims this triangle is a right triangle and tries to justify it using the converse of the Pythagorean Theorem. Which of the following best evaluates the student’s claim?
A) The student is correct because 7^2+24^2=25^2, proving the triangle is right.
B) The student is incorrect because 7^2+24^2 not equal to 25^2, so the triangle cannot be right.
C) The student is incorrect because all side lengths must be equal to prove a triangle is right.
D) The student is correct because any triangle with side lengths less than 30 cm is a right triangle.
