By the end of this unit of work you should be able to do the following:

  • Identify, name, measure and draw six different types of angles (acute, right, obtuse, straight, reflex and revolutions)
  • Identify, name, measure and draw six types of triangles (acute, right, obtuse, equilateral, isoceles and scalene)
  • Identify and name six different quarilaterals (square, rectangle, rhombus, parallelogram, trapezium and kite)
  • Identify and draw perpendicular and parallel lines
  • Identify and calculate vertically opposite, alternate, corresponding, complementary, supplementary and co-interior  angles.
  • Calculate missing angles in triangles and quadrilaterals.
  • Accurately draw regular polygons and calculate angles in regular polygons.

Each of the following activities matches with specific learning outcomes.
