Use similarity transformations to establish the AA similarity criterion.

Match two angle pairs for AA similarity

Problem

For the \(\text{two}~\text{supplied}~\text{triangles}\), calculate any missing third angles, identify \(\text{two}~\text{equal}~\angle~\text{pairs}\), map \(\text{all}~\text{three}~\text{vertices}\), and write the ordered \(AA\) similarity statement.

Neutral triangle angle-measure reference listing triangle GHJ angles G 90 degrees and H 35 degrees, and triangle KLM angles K 35 degrees and L 55 degrees, without third angles or correspondence mapping. Open full size
