• Different lines and angles have specific names according to their environment, position, size, measurement, etc. This section provides some common definitions for lines and angles.
• The shortest distance between two points is a straight line. The distance between points (x1, y1) and (x2, y2) is given by:
The coordinates of the midpoint between the two points are:
(x1 + x2)/2 and (y1 + y2)/2
