Identify Corresponding Angles

There are lots of different angles to be found between parallel lines.

Here we are going to look at corresponding angles.

We find them in parallel lines on the same side of the transversal (the line that goes through the middle of the parallel lines).

Review the two diagrams below showing corresponding angles:

As we can see in the diagrams above, corresponding angles sit either below or above the parallel lines.

They also look like the letter F.

We could also say that they are in matching corners, so the word 'corresponding' can be linked to 'corners'. 

The really hard part is spotting corresponding angles in diagrams.

Once we find them, we can apply the rule that these angles are always equal. 

Right then, let's get investigating now. 

In this activity, we will learn how to recognise corresponding angles and use the key fact, that corresponding angles are equal, to find the value of unknown angles and solve related problems.
