Question

Which of the following is a right triangle?

A.
a triangle with sides measuring 13, 15, and 19
B.
a triangle with sides measuring 17, 25, and 36
C.
a triangle with sides measuring 20, 21, and 29
D.
a triangle with sides measuring 18, 23, and 41

Answer 1

Explanation:

the right choice is C

you use c^2=a^2+b^2

where the largest side is the hypotenuse

Answer 2

C.

a triangle with sides measuring 20, 21, and 29

Explanation:

As, √(20)²+(21)² = √400+441 = √841 = 29

The longest side is taken as the hypotenuse. So 29 is the hypotenuse. Which by using Pythagoras' theorem gives us 29 ( h=√b²+p² )
