1. Midsegment Theorem
Chapter 5 addition

2. Midsegment of a Triangle
Connects the two midpoints of two sides of a triangle.
Midsegment

3. Midsegment Theorem
The midsegment connecting the midpoints of two sides of the triangle is parallel to the third side and is half as long. C E B D A
DE // AB
and
DE = AB

4. TEST QUESTION (worth ~12% of your test grade)
Verify that both parts of the Midsegment Theorem are true for segment DE. Show and label your work very neatly and clearly!

TEST QUESTION
Show that DE // AB
Find the slopes of segments AB and DE 8 6 4
The slopes are = so the lines are // 3
