MIDSEGMENT LAB
Work in groups of 4You will have 25 minutes to complete lab.
MIDSEGMENT THEOREM
Definition: The segment connecting the midpoints of two sides of
a triangle is parallel to the third side and is half as long as that side.

CHECKPOINT
All lines inside triangle ABC are midsegments.
1.What is the midsegment of AB: ______2.Line FE is parallel to _____3.Line FD is parallel to _____4.Line DE is parallel to _____5.If FE = 5, then AB= ____6.If FD=10, then CE= ____7.If AB=30, then FE= ____8.If CA=12, then DE=_____
GUIDED EXAMPLE
If MP=2x-1, and BC=3x+5, what is MP and BC?
If AD= 2x+4 and DB=3x-1, what is FE?
