# Angle ABC (notation)

Alternative Versions: ∠ABC or a ^ over the middle letter.

The angle made between sides AB and BC. The angle can always be found at the middle letter.

Example: The angle ABC is marked with an x.

# ABC (Notation)

The shape made by joining the vertices A, B and C. Capital letters are used for each of the vertices.

**Note: **The number of letters represents how many corners the shape has. ABCD would represent a four sided shape.

Example: Triangle ABC has three marked angles.

# A (Notation)

A capital letter is used to name a particular point on a graph or diagram. Any letter can be used to represent a point, however some letters have particular meanings.

O = Origin (0,0)

M = Midpoint

Example: This triangle has three points: A, B and C.
