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 <u>G</u>oogle: They're always right. (jk no that's not true neither are always right)
