# Angles and Parallel Lines

### Angles and Parallel Lines

When lines are parallel, angles around them follow rules which we can use to find unknowns.

Parallel lines continue in the same direction as each other, forever, without touching. Therefore, they remain the same distance apart from each other at all times.

There are 4 main rules for angles in parallel lines which we can use to solve geometrical problems.

An angle around a point on a parallel line is $95\degree$. What is the corresponding angle on the other parallel line?

What do we call angles that form a 'Z' shape on parallel lines?

Complete the sentence: Co-Interior angles...

Often we will need to apply multiple angle rules in order to solve a problem. The following examples will show you how to do this.

Which of these statements is not true for parallel lines?
