Worksheet Overview

In this worksheet, you will measure angles and use this to identify which type of angle they are.

An angle measures the rotation of one line segment on to another and they are measured in degrees°.



Are they acute (less than 90°), a right angle (= 90°), obtuse (between 90° and 180°) or reflex (more than 180° and less than 360°)?


1. AB is turned through 50° to coincide with AC. The angle is labelled BAC and is acute.


2. A quarter rotation measures 90° and is marked with a square. Angle BAC is also a right angle.


3. A half rotation measures 180°.


4. A complete rotation measures 360°.
