A midpoint cuts a line or a side in half.
Theorem: If a segment joins the midpoints of two sides of a triangle, then the segment is parallel to the third side of the triangle and is half as long.
Find the values of the midsegments: 30 40 50
A median of a triangle is a segment whose endpoints are a vertex and the midpoint of the opposite side.
The point of concurrency of the medians is called the CENTROID.
BREAK THE MEDIAN INTO THIRDS 2 of the THIRDS are the LONGER PIECE 1 of the THIRDS is the SMALLER The smaller is always HALF of the BIGGER piece 1/3 2/3
