About Geometry Worksheet Assignment 4.20:        

 

Assignment 4.20 is an introduction to midsegments of triangles.

 

Prerequisite Skills:  Measure line segments (Assignment 1.11).  

 

Definition:     A midsegment of a triangle is a line segment with endpoints at the midpoints of two sides of the triangle.

 

Theorems:   A midsegment of a triangle is parallel to a side of the triangle.  

                           The length of the midsegment is one-half the lengths of the side to which it is parallel.
