Angle Pairs Game - Beat the Clock
Aim: The purpose of this game is to recognise the equal and supplementary angles formed when a transversal cuts a pair of parallel lines. It also aims at learning the correct names for the pairs of angles.

Instructions: Press the START button. A pair of angles will be displayed on the diagram. Decide first if they are "equal" or "supplementary" then press the appropriate button. If correct a tick will appear next to the box. Then decide on the correct name for the pair of angles and press the appropriate button. When the time (20 seconds) is up, the game stops until "reset".
