This activity 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.

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 of a square or rectangle.
Also, right angles are often labelled with a square corner, like the one in this example.
Shall we have a go at some questions now?
