Basics of angles for AQA GCSE Maths
This page covers the following topics:
1. Introduction to angles
2. Angles at a point, on a straight line
At a point where two lines meet or cross, an angle will be created. Angles can be labelled and written using letters as shown.
The angles around a point add up to 360° and angles on a straight line add up to 180°.
If the angle around a point is a full circle, what are the size of the angles at the centre of a semi-circle?
How would you write the angle shown using the letters given?
YXZ or YX̂Z or ∠YXZ
An angle is split with a line through the middle so that two angles of 47° are created. What is the size of the overall angle?
Calculate the value of x in the angle shown.
Calculate the size of angles A and B, given that the line XY cuts the circle around the point in half.
A = 73°, B = 127°
