Transversals Worksheets
What are Transversals? A transversal is when two parallel lines are intersected by the third line at an angle. The line intersecting the two parallel lines; the third line is known as the transversal line. We get different types of angles when a transversal line passes through the parallel lines. Some of the commonly known angles are defined below: Supplementary angles  When pair angles are added together and give us a measure of 180 degrees, we get supplementary angles. When we put the pair of supplementary angles together, we can draw a straight line across the two angles. Or simply put, the two angles, when put together, will make a halfcircle. Also, the supplementary angles arenâ€™t limited to transversals. Interior Angles  As the name implies, angles present interiorly, on the inside, of the two parallel lines are known as the interior angles. Exterior Angles  Angles present on the outside of the two parallel lines are known as the exterior angles. Corresponding Angles  Angles that are present on the same side of the transversal line are known as the corresponding angles. In corresponding angles, one angle is an interior angle while the other is the exterior angle; these angles are equal in measurement and are congruent.

Basic Lesson
Guides students through the skill of location transversals. A line which intersects two or more lines at different points is called a transversal to the given lines.

Intermediate Lesson
Demonstrates how to locate transversals. Three lines CB, FE and AD are in same plane. Line AD intersects BC and EF. A line which cuts two or more lines in a plane at different points is called a transversal.
