Question

Is 13 cm, 14 cm, and 15 cm a right triangle?

Answer 1

Answer:

Not a triangle

Step-by-step explanation:

First you have to use the Pythagorean theorem

a^2 +b^2=c^2

13^2+14^2=15^2

13*13=169

14*14=196

15*15=225

169+196=225 is not true

This IS NOT a right triangle

I hope this helps!
