Question

Is this triangle a right triangle? yes or no?

Answer 1

Yes.

Explanation:

You can use the Pythagorean theorem to figure this out.

5²+12²=13²

25+144=169

169=169

You can also look at the bottom left corner, which is a right angle. All triangles containing right angles are right triangles.

You can also base your answer off of the fact that triangles are kind of like Google: They're always right. (jk no that's not true neither are always right)
