Overview
This lesson will teach you how to use midsegment properties to solve problems.
A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle.
Essential Understanding
Two unique relationships exist between the triangle's midsegments and the triangle's third side. You can observe patterns in some number sequences and some sequences of geometric figures to discover relationships.
