GCSE Maths Practice: polygons

Question 8 of 10

This question asks which regular polygon has interior angles of 90°.

‹ ›

\( \begin{array}{l}\text{Which regular polygon has interior angles of } 90^\circ?\end{array} \)

Choose one option:

\( \text{Square} \) \( \text{Pentagon} \) \( \text{Hexagon} \) \( \text{Octagon} \)

Check that the polygon has four equal sides and 90° interior angles.

A square is a four-sided regular polygon with equal sides and all interior angles equal to 90°. Knowing this allows students to identify the polygon, calculate properties like perimeter, area, and angles, and solve related geometry problems. Recognizing the relationship between the number of sides and the size of interior angles is fundamental in GCSE geometry. Practising this builds fluency for identifying shapes in diagrams and solving polygon-based problems efficiently.
