Riddle Me This: Parallel and Perpendicular Lines

Don’t get tricked by parallel and perpendicular lines in this playful worksheet! Students will be asked to look at six pairs of lines and decide whether each pair is parallel, perpendicular, or both. Then, they’ll use the letter that corresponds with their answer to fill in the blanks at the bottom of the page and find the answer to the riddle. 

This fourth-grade worksheet is sure to engage students as they solve a puzzle and practice identifying parallel and perpendicular lines, a foundational geometry skill. Confidence in determining whether lines are parallel or perpendicular can improve students’ ability to recognize patterns in geometry and set them up to learn trickier geometry skills in the future.
