AET - Visualisation Activity 9 Imagine two parallel lines of infinite length … Make them horizontal, not too far apart. Keep them fixed in this position. Imagine a vertical line which crosses the parallel lines … Think to yourself: How many points of intersection can I see? … Can you see eight angles? Count them to make sure. Now very slowly rotate the vertical line clockwise. As you slowly rotate the line, think to yourself: What happens to the angles? … Which angles are equal?
