There was a bit of confusion when I posted this question to twitter. The angles marked with an arc are not indicating that the angles are the same size. Instead, the arcs are there to indicate which angles we are finding the sum of in each diagram.

A commenter on twitter said that this type of question used to be standard fare on the SAT in the 1970s and 1980s.
