GCSE Maths Practice: triangles-and-quadrilaterals

Question 7 of 10

This question tests knowledge of interior angles in a square.

‹ ›

\( \begin{array}{l}\text{What is the size of each interior angle of a square?}\end{array} \)

Choose one option:

All angles in a square = 90°; visualize the corners.

A square is a quadrilateral with four equal sides and four right angles. Each interior angle is 90°. Understanding this property is essential for identifying squares, calculating missing angles in composite shapes, and solving geometry problems. Squares appear in real-life applications such as tiles, floor plans, and geometric diagrams. Knowing the measure of interior angles also helps when calculating sums in polygons, using the formula (n-2) × 180°, where n is the number of sides. Practicing with squares and other quadrilaterals improves visualization skills, geometric reasoning, and accuracy in exams. Drawing and labeling squares reinforces knowledge of side lengths and angle measures. Recognizing right angles in diagrams allows students to solve problems quickly and confidently in GCSE geometry tasks.
