1. Section 5.1- Midsegments of Triangles
Coach Douglas- Geometry
November 30th

2. Objective I will use the properties of mid segments to solve problems.
Begin warm up on 5.1 notes.

3. Midsegment
A segment that connects the midpoints of two sides of a triangle.
D is the midpoint of side BA.
E is the midpoint of side AC.
Line DE is a midsegment of ΔABC.

4. Midsegment Theorem The midsegment theorem makes two statements:
1) Each midsegment is parallel to a side of triangle.
2) The length of a midsegment is half the parallel side.

5. Using the Midsegment Theorem
Midsegment DE is parallel to side BC
The length of DE is equal to half of BC.
DE= 1/2 *BC
