A transversal is a line, line segment, or ray that intersects through two or more lines at distinct (different) points.

Corresponding angles are a pair of angles at different vertices on the same side of a transversal in equivalent positions.

Alternate angles are a pair of angles, both between or both outside two line segments, that are on opposite sides of the transversal that cuts them.

Co-interior angles are on the same side of the transversal line and in between the two other lines.

A bearing is an angle measured in degrees from North in the clockwise direction and written with three figures.
