'Know Your Angles: Smallest or Largest?' worksheet

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.

 

An angle 3 angles 3 angles
1
2
 3

 

Answer

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.
