a segment that connects the midpoint of two sides of a triangle that never intersect
Triangle Midsegment Theorem
If a midsegment in a triangle is drawn, then that segment is para. to the third side and is half as long
Median
A segment whose endpoints are vertex and the midpoint of opposide sides
Concurrent lines
three or more lines that intersect at the same point
Point of Concurrency
The point where concurrent lines intersect
Centroid
Point of concurrency for medians
Concurrency of medians theroem
The centroid in 2/3 the distance from the vertex to the midpoint of the opposite sides
Vertex
The corner where the median starts
Altitude
A segment drawn from the vertex that is perp. to its opposite side
