Angle - GCSE Maths Definition

An angle is a measure of the amount of turn between two straight lines that have a common end point, known as the vertex. Angles are measured in degrees (°) and are an essential part of geometry, a key area in GCSE Maths. Common types of angles include acute angles, which are less than 90°, right angles that are exactly 90°, obtuse angles between 90° and 180°, and reflex angles which are greater than 180°. Understanding angles is fundamental in solving problems related to shapes, trigonometry, and various real-world applications.
