1. Please get a warm up and begin working.

2. Midsegments of Triangles
A segment whose endpoints are the midpoints of two sides.
It is parallel to one side of the triangle
The measure is ½ of that side.
Midsegments of Triangles
If AE = 15
Find the measure of BD A B C D E X
½ X
midsegment
BD = 7.5

3. TRY THIS AND THIS 3X - 5 X + 2 A B C D E 3X – 5 = 2(X + 2)
AE = 22 units
BD = 11
X2 + 1 = 2 (X)
X2 – 2X + 1 = 0
(X – 1) (X – 1) = 0
X = 1
BD = 1 units
AE = 2 units
AND THIS A B C D E
X2 + 1 X

4. Find the lengths of BD and AE if
Uno mas
Find the lengths of BD and AE if
BD = 4x – 4 and AE = 10x – 12
2(4x-4) = 10x – 12
8x – 8 = 10x -12
4 = 2x
X = 2
BD = AE = 8 B C D E A

5. Please get a piece of patty paper and a straight edge
Create a large triangle, call it ∆ABC
Find the midpoints of each side.
Create the midsegments.
State which sides are parallel.
