Angles

In this section the activities are looking at angles. Angles are very important in maths, and there are some key principles needed. as shown here.

Two activities in one here. Practise estimating the size of angles and making target angles until you are a real angle pro!

Test your knowledge of how to find Angles on a Straight Line.

Can you calculate the missing angle using your knowledge of angles round a point?

What do you know about the angles in a triangle? Use this knowledge to calculate the size of the missing angles.

Given three angles in a quadrilateral, what is the fourth? Does it matter whether the quadrilateral was a rectangle, parallelogram or trapezium?

Investigate the size of angles in any regular polygon, and more importantly the sum of all the angles in any polygon.

A great starter to a lesson, you must remove as many angles as you can without losing any information.
