In this lesson we will learn how to find angles on parallel lines using the rule of alternate angles and you will learn how to gain full marks when answering these types of questions. This lesson has specially edited using special software so that there is a section in the middle of each example where the alternate angles and the lines that make those angles are highlighted in bright red. This makes them stand out so that you can easily see where they were hiding amongst all of the other angles and lines. Because of the way this lesson is edited you will find this lesson very easy to learn.

The questions covered in this lesson are i) find angle $x$, give a reason for your answer.
