Question

What is the length (c) of the hypotenuse of the right triangle?

A. 12 feet
B. 13 feet
C. 17 feet
D. 25 feet

Answer 1

c is equal to the square root of the sum of the squares of the two sides. Is that clear to you?

Answer 2

Yes :)

Answer 3

What is the answer you get then? :)

Answer 4

60?

Answer 5

Ok here. The sum of the squares means 5^2 + 12^2, right? And that is-?

Answer 6

Oh okay that's 169

Answer 7

Yup. So the square root of that is-?

Answer 8

That would be 13

Answer 9

Yup and that's your c! See, this is Pythagoras's theorem that says the hypotenuse of a right angle triangle is the square root of the sum of the squares of the other two sides. :)
