Question

Help please !Which triangles are similar?

(pls don’t answer if you don’t have the answer I will report you...)

Answer 1

A and B are similar.

Explanation:

All three angles of a triangle add up to 180°.

C isn't like the others because if you add up 30 and 25, and subtract that from 180, it equals 125, and the angle on the other triangles are 135°.

a and b are similar triangles
