Here are some additional geometric symbols.

Properties of Angles

Oftentimes questions require the determination of the size of an angle along with the reason for your answer. When stating the reason, the property used needs to be indicated (calculations alone do not constitute a reason).

NB: Diagrams are NOT TO SCALE. Therefore solutions by measurement are not allowed.
