In this unit of work students are introduced to a range of angle properties including angles on a straight line, in a triangle and vertically opposite. Students are guided to discover each of the angle properties for themselves so they can link them together later on.
This unit takes place in Term 5 of Year 7 and is the prerequisite unit for angles in parallel lines and exterior angles in polygons which students cover in Year 8.
How to introduce the sin, cos and tan trigonometric identities.
