This task is used as a warmup in geometry classes. The task focuses on classifications of triangles, and the postulates that come with the relationships between side lengths and angles. One problem asks students to construct an argument about scalene triangles and their angles. Students are also asked to find the midpoint of a line segment on a coordinate plane.
