Description:

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Rhianna has learned the SSS and SAS congruence tests for triangles and she wonders if these tests might work for parallelograms. Suppose $ABCD$ and $EF...
