Assignment 2.14 is an introduction to transversals and pairs of angles determined by transversals.

 

Prerequisite Skills: Name lines (Assignment 1.1).  Name angles (Assignment 2.4).  

 

Definitions:  A transversal is a line that intersects two lines in a plane.

 

                           For two lines intersected by a transversal: 

                           An Interior angle is an angle in which the vertex is one intersection and the other intersection lies on one of its sides.

                           Alternate interior angles are a pair of interior angles that are on opposite sides of the transversal and are not a linear pair.

                           Corresponding angles are a pair of angles on the same side of the transversal that are not a linear pair and exactly one of the angles is an interior

                           angle.

                           Same side interior angles are interior angles on the same side of the transversal.
