In this worksheet, we will learn about parallel lines.
Parallel lines run in the same direction and are marked by arrow heads, as above. They never meet.
Parallel lines which are intersected by an oblique line give rise to sets of equal angles.
The two angles marked in diagram (a) are equal.
They are corresponding angles and can be found in an F-shape which is rotated. Can you find three other pairs of corresponding angles?
The two angles in diagram (b) are equal and are alternate angles and can be found in a z-shape,
