Symbols to describe angles:

Arrowheads on the lines mean that the lines keep on going. The length of an angle's arms does not change the size of the angle. Whether the arms are long or short, the angle size stays the same.

There are two angles at a vertex so it is important to show which one we are talking about

You can name the angle on the right in different ways: you can say AB^C or CB^A or just B^. The 'hat' on the letter shows where the angle is.
