horizontal and vertical lines

Median - Recall a line segment joining the vertex to the mid-point of the opposite side of a triangle. In D ABC, AD is the line segment drawn from A to BC (opposite side of A). AD is a median of a triangle. "The line segment jointing a vertex of a triangle to the mid-p..
