Equation for sides of a triangle

WebThe median connects a vertex to the MIDPOINT of the opposite side. If you have the point for the vertex (first point) you just need to find the midpoint of the opposite side (second point) and find the slope using these two points. To find midpoint average the xs and average the ys to create a new ordered pair.
