00:00 Are the triangles similar?
00:03 Isosceles triangle according to the given
00:07 In an isosceles triangle, base angles are equal
00:11 Sum of angles in a triangle equals 180
00:15 Therefore the third angle equals 180 minus the known angles
00:20 Equal angles according to the given
00:26 Let's substitute the angle value
00:35 Isosceles triangle according to the given
00:39 In an isosceles triangle, base angles are equal
00:44 The angles sum to 180
00:48 Therefore each angle equals A
00:53 Equal angles (EA)
01:01 The triangles are similar by AA
01:11 And this is the solution to the question
