3 Teaching angle measures and angle facts

Learners struggle with the idea of angle being a measurement of turn and also a measure of the gradient between two lines. In particular, learners can be distracted by the lengths of the lines which make up the angles. The angles between the two sets of lines shown in Figure 8 may be considered to be different even though the angle of turn from one line to the other is the same.
