GCSE Maths Practice: angles

Question 5 of 10

This question focuses on exterior angles of regular pentagons.

‹ ›

\( \begin{array}{l}\text{What is the exterior angle of a regular pentagon?}\end{array} \)

Choose one option:

Divide 360° by the number of sides to get each exterior angle.

For a regular pentagon, all sides and angles are equal. The exterior angle is found by dividing 360° by the number of sides: 360 ÷ 5 = 72°. Knowing exterior angles helps solve polygon geometry problems, including interior angles (interior + exterior = 180°). Understanding these angles is key for designing regular shapes, tessellations, and understanding symmetry. Practicing exterior angle calculations improves diagram reading, geometric reasoning, and exam performance. Real-life applications include architecture, tiling, and polygons in art. Students should practice exterior angles for polygons with different side counts to master the concept.
