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.
