Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*

A. 5^2+4^2=41
8^2=64
64 doesn’t =41 therefore triangle A isn’t a right angle
B.9^2+12^2=225
15^2=225
225=225 therefore triangle b is a right angle
C.5^2+12^2=169
13^2=169
169=169
Therefore triangle C is a right angle.

Hope this helps
