Sample problems
- Two parallel lines are cut by a transversal. One angle measures 95°. What is the measure of its corresponding angle? 95°
- Two parallel lines are cut by a transversal. One angle measures 117°. What is the measure of its co-interior angle? 63°
- Two parallel lines are cut by a transversal. One angle measures 43°. What is the measure of its corresponding angle? 43°
- Two parallel lines are cut by a transversal. One angle measures 61°. What is the measure of its alternate interior angle? 61°
- Two parallel lines are cut by a transversal. One angle measures 71°. What is the measure of its corresponding angle? 71°
- Two parallel lines are cut by a transversal. One angle measures 37°. What is the measure of its corresponding angle? 37°
- Two parallel lines are cut by a transversal. One angle measures 53°. What is the measure of its corresponding angle? 53°
- Two parallel lines are cut by a transversal. One angle measures 110°. What is the measure of its alternate interior angle? 110°
These eight are one sample at medium difficulty — the generator makes a different set every time.
A worked example
Two parallel lines are cut by a transversal. One angle measures 95°. What is the measure of its corresponding angle? 95°
- Corresponding angles on parallel lines are equal
- So it is 95°

About these worksheets
Each problem states its own measurements, so the reasoning is the same but the arithmetic is new every time. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.
Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
