2.) △ABC is similar to △GHI by ​AA Similarity Postulate​.

3.) △ABC is similar to △JEL by ​AA Similarity Postulate​.

​4.) △ABC​ is not similar to any of the triangles given.

Answer 1

Similarity means same angles.

note that the sum of all inner anglin a triangle is always 180° in flat 2D space.

Only option C has a chance to be correct.

and its indeed correct, bc 180-65-65 = 50
