What It Is: A visually clear and student-friendly worksheet focused on identifying unknown angles in pairs of supplementary angles. Each problem shows one known angle and one missing angle on a straight line, helping students apply the rule that supplementary angles add up to 180°. Why Use It: This worksheet strengthens understanding of straight-line angle relationships and builds essential geometry skills. Students practice subtracting from 180°, reinforcing both angle reasoning and basic algebra. Perfect for review, independent practice, or classroom warm-ups. How to Use It: • Explain that supplementary angles always total 180°. • Have students subtract the given angle from 180° to find x. • Use as practice during lessons on angle pairs, linear angles, or introductory geometry. • Ideal for guided practice, homework, early finisher tasks, or assessment. Grade Suitability: Best suited for Grades 4–6. • Grade 4: Introduction to straight-line angles and decomposition of angles. • Grade 5: Reinforces angle relationships and reasoning. • Grade 6: Supports pre-algebra and multi-step geometry problems. Target Users: Teachers, students, tutors, homeschoolers, and learners reviewing supplementary angles and linear pairs.

Practice solving for missing angles in linear pairs with this supplementary angles worksheet. Students find unknown angles that add up to 180°. Great for Grades 4–6.
