GCSE Maths Practice: angles

Question 9 of 10

This question reviews sum of angles in different shapes.

‹ ›

\( \begin{array}{l}\text{Which statements about angle sums are correct?}\end{array} \)

Select all correct options:

Apply the sum rules for each shape carefully and double-check totals.

The sum of angles varies depending on the shape. In a triangle, the angles always sum to 180°. On a straight line, angles sum to 180° as well. Around a point, all angles sum to 360°. In a quadrilateral, angles sum to 360°, not 270°. Knowing these rules helps students solve problems involving unknown angles, polygon properties, and geometric constructions. Practicing different shapes and applying the sum rules enhances diagram reading and calculation accuracy. These principles are foundational in geometry and are frequently tested in GCSE exams. Recognizing and applying these sums correctly helps in proofs, constructions, and real-life applications, such as architecture or design layouts.
