This task requires students to calculate the size of angles using their knowledge of angles and parallel lines: alternate angles, corresponding angles and co-interior angles. Understanding of adjacent angles on a straight line is also required.
Using the context of carpark lines, students are required to apply their knowledge of angles on parallel lines to calculate unknown angles and identify a non-parallel line from a selection of lines.
Students use their knowledge of the interior angles of regular polygons, isosceles triangles, and parallelograms to work out unknown angles for a variety of 2-dimensional shapes.
