Question

Which are the dimensions of a right triangle?
A. 4 cm, 7 cm, 10 cm
B. 6 cm, 8 cm, 9 cm
C. 8 cm, 12 cm, 16 cm
D. 9 cm, 12 cm, 15 cm

Answer 1

If the dimensions satisfy the Pythagorean Theorem equation, then the triangle is a right triangle.
\[A^2 + B^2 = C^2\]
Where A and B are the shorter sides, and C is the longer side.

I advise you to test each choice.

Answer 2

C is the longest side*

Answer 3

Do 'A^2 + B^2' for each choice. See if it is equal to C^2.

Answer 4
