## Midsegments of Triangles

#### Activity Overview

In this activity, students will explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle. First, students will construct and investigate one midsegment and the relationship of the new small triangle to the original triangle. Then, all three midsegments will be constructed and this figure will be explored.

#### Key Steps

• First, students will construct and investigate one midsegment and the relationship of the new small triangle to the original triangle.

• Then, all three midsegments will be constructed and this figure will be explored. Students will explore the relationship between the original triangle and the midsegment triangle.
