Revise: Angular MeasuresAn angle measures the amount of turn between two lines meeting at a point. It does not depend on how long the lines are. In design and technology, angles help you specify the slope of a component, mark out a shaped piece of material or create a repeating pattern accurately.
Show angle calculations and name the rule used, such as ‘corresponding angles are equal’ or ‘angles on a straight line total 180°’.
Use given angles and geometric relationships rather than measuring a diagram unless measurement is requested.
For tessellations, check that angles meeting at a vertex total exactly 360°. Also check that the repeated shapes leave no gaps or overlaps.
