  # Know Your Angles: Smallest or Largest?

In this worksheet, students identify the largest and smallest angles from a choice of three. Key stage:  KS 2

Curriculum topic:   Geometry: Properties of Shapes

Curriculum subtopic:   Recognise Angles

Difficulty level:   #### Worksheet Overview

This worksheet is about identifying the largest and smallest angles.

We can identify angles as follows: right angles (90 degrees), acute angles (smaller than a right angle), or obtuse angles (larger than a right angle).

Example

Identify the largest and smallest angles.   1
 2
 3

The smallest angle is 1.  It is smaller than a right angle, so we call this an acute angle.

The largest angle is 2.  It is larger than a right angle, so we call this an obtuse angle.

Angle 3 is a right angle.

It is smaller than angle 2 but larger than angle 1.

We can spot a right angle by imagining the corner or a square or rectangle.

Also, right angles are often labelled with a square corner, like the one in this example.
