Quotes from the NZC http://www.nzmaths.co.nz/elaborations-level-five-geometry-and-measurement
AO1: Deduce the angle properties of intersecting and parallel lines and the angle properties of polygons and apply these properties.
The angle properties of lines are:
1.Vertically opposite angles are equal
2.Adjacent angles add to 180
3.Corresponding angles are equal
4.Interior angles add to 180
5.Alternate angles are equal
1.Interior angles of a polygon with n sides are ((n-2) x 180)/n.
2.Exterior angles of any polygon add to 360.
