Endpoints and Midpoints
Use coordinates to find the endpoint of a line segment
Use the semi-segments (from endpoint to midpoint) to find the ordered pair of the other endpoint of each segment. The first point in each given semi-segment is an endpoint.
Find the point on a directed line segment between two given points that partitions the segment in a given ratio.
