Define a corresponding angle and draw the diagram.

A corresponding angle is an angle that is in the same position in relation to a pair of parallel lines and a transversal. Corresponding angles are congruent, meaning they have the same measure.

--------------------- parallel lines

```

In the diagram above, angle A and angle C are corresponding angles as they are in the same position in relation to the parallel lines and the transversal.

Definition:

In geometry, a corresponding angle is one of two angles that are in the same relative position in different figures or shapes. They are formed when two or more parallel lines are cut by a transversal.

Diagram:

Consider the following diagram:

[Image of a diagram with two parallel lines (AB and CD) cut by a transversal (EF)]

In this diagram:

- AB || CD (AB is parallel to CD)
- EF intersects AB at point G
- EF intersects CD at point H

The following angles are corresponding angles:

- ∠AGB and ∠CHD
- ∠BGE and ∠DHE

Explanation:

Corresponding angles are created when a transversal intersects two parallel lines. They are located on the same side of the transversal and on the same side of the two parallel lines. In the diagram above, the transversal EF intersects the parallel lines AB and CD, creating corresponding angles ∠AGB and ∠CHD, as well as ∠BGE and ∠DHE.
