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 half-circle. Also, the supplementary angles aren’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.
