Please get a warm up and begin working.

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

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

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 = 4 AE = 8 B C D E A

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.
