 # Angle Labelling

In this worksheet, students label angles using the correct three letters. Key stage:  KS 3

Curriculum topic:  Geometry and Measures

Curriculum subtopic:  Use Standard Conventions for Labelling Triangles

Difficulty level:   ### QUESTION 1 of 10

Angles are labelled using three letters as shown in this example.

The middle letter must be the one at the apex of the angle.  The other two letters are from the ends of the angle's arms. Written properly, the angle shown above is labelled as ∠BAC or  ∠CAB.

It can also be written as BÂC or CÂB.
