1

Corresponding angles

Angles that are in the same relative position at each intersection where a straight line crosses two others.

2

Corresponding angles rule

If two parallel lines are crossed by a transversal, the corresponding angles are equal.

3

Transversal

A line that crosses two or more other lines.

4

Parallel lines and corresponding angles

Corresponding angles are equal when the lines are parallel.

5

Shape formed by corresponding angles

Corresponding angles form an 'F' shape when the lines are parallel.

6

Example of corresponding angles

If one corresponding angle is 50°, the other corresponding angle is also 50°.

7

Non-parallel lines and corresponding angles

If the lines are not parallel, corresponding angles are not necessarily equal.

8

Identifying corresponding angles

Look for angles in matching corners of the 'F' shape formed by the transversal and parallel lines.

9

Real-life example of corresponding angles

Corresponding angles can be seen in railway tracks crossed by a bridge or road.

10

Reason for corresponding angles being equal

This is due to the parallel nature of the lines and the consistent spacing between them.
