Which triangle is ​△ABC​ similar to and why? △ABC is similar to △DEF by ​ AA Similarity Postulate ​. △ABC is similar to △GHI by ​ AA Similarity Postulate ​. △ABC is similar to △JKL by ​ AA Similarity Postulate ​. ​△ABC​ is not similar to any of the triangles given. NOTE: Figures are not drawn to scale. Four triangles are given. Triangle A B C, triangle D E F, triangle G H I, and triangle J K L. Angle A is 20 degrees. Angle B is 80 degrees. Angle D is 18 degrees. Angle E is 80 degrees. Angle G is 20 degrees. Angle H is 70 degrees. Angle K is 80 degrees. Angle L is 80 degrees.

Question
Answer:
The answer would be,  it is  △JKL by ​ the AA Similarity Postulate.

Explanation for this would be:
For ΔABC 
m∠A + m∠B + m∠C = 180°
20° +   80° + m∠C = 180°
100° + m∠C = 180°
m∠C = 80°
Therefore, the two angle pairs are congruent ⇒ △ABC ~ △JKL
