Interior Angles in Parallel Lines Worksheet

This printable worksheet, thanks to its nine questions that afford children extensive practice on identifying and finding the measures of the interior angles, allows students an opportunity to hit the big time. The interior angles that lie on the same side of the transversal are consecutive interior angles, and those lying on either side of the transversal are alternate interior angles. The consecutive interior angles are supplementary, and the alternate interior angles are congruent. Use these properties of the angle pairs to find the value of x.

The worksheet is specially designed for students of grade 8 and grade 9.
