Angles of Regular Polygons is a Grade 8 mathematics worksheet that develops students’ ability to determine the sum of interior angles and the measure of one interior angle in regular polygons. The 11-item set includes 10 multiple-choice questions and one fill-in-the-blank question covering triangles, hexagons, octagons, and other polygons, along with the meanings of regular polygon and congruency. Students apply angle reasoning to identify total interior-angle measures, solve for a single angle, and distinguish between related geometric definitions. Use this free printable worksheet for guided practice, independent work, review, or a quick check of understanding after teaching regular polygons. The varied items move from foundational facts about triangles and congruent figures to calculations involving polygons with different numbers of sides, helping teachers see whether students can transfer the idea across examples. A complete answer key is included for efficient checking and feedback.

This Grade 8 worksheet covers finding the sum of interior angles and the measure of one interior angle in regular polygons. Its 10 multiple-choice items and one fill-in-the-blank item ask students to work with triangles, hexagons, octagons, and other polygons while also identifying regular polygons and congruent figures. Completing the set helps students distinguish a polygon’s total interior-angle sum from the measure of each individual angle.
Begin by reviewing the meanings of regular polygon and congruency, then model the difference between a polygon’s total interior-angle sum and one interior angle. Work through a triangle example before comparing the hexagon and octagon questions, asking students how the number of sides affects their calculation. Use the multiple-choice options to prompt students to explain why a tempting answer represents the total sum rather than a single angle.
Students may confuse the sum of all interior angles with the measure of one interior angle, especially when both types of questions appear together. Watch for errors in identifying the number of sides in the polygon diagrams, choosing an answer for a regular polygon without checking that all sides and angles are congruent, or selecting a familiar angle measure without applying it to the specified triangle, hexagon, or octagon. The fill-in-the-blank item also checks whether students can record the total angle sum accurately rather than relying only on recognition.
On Wayground, assign it as a printable PDF or as a digital quiz, depending on how you want students to complete the 11 angle and terminology questions. The worksheet includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also gives schools an option for reducing screen time.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the polygon-angle questions and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those changes support access to the geometry vocabulary and calculations. These options modify the worksheet file while preserving its multiple-choice and fill-in-the-blank format.
