Angle Properties

This worksheet is an attempt to get students comfortable with algebra, angles and proof. This starts with angles around a point and on a line and asks students to write down any relationships between angles. We then move on to polygons (including triangles) and look for relationships. The next stage is parallel lines and their angle properties, asking studetns to write angles in terms of another angle. Finally we have circle theorems and some simultaneous equations moving on to a couple of proofs. This should generate discussion and is designed to do so, especially the parts involving algebra plus the need to explain the angle property used in each case.
