Question

Do 5 feet+ 12 feet + 13 feet make a. Right triangle

Answer 1

yes

Explanation:

Pythagoras

in a right triangle it is always

c² = a² + b²

with c being the side opposite of the 90 degree angle.

5² = 25

12² = 144

13² = 169

so, because indeed 13² = 5² + 12², these three lines make a right triangle.
