Warm Up: Corresponding Angles

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

The corresponding angles are equal.

Front

Identify a pair of corresponding angles from the following: ∠1 and ∠5, ∠2 and ∠6, ∠7 and ∠8.

Back

∠7 and ∠8 are corresponding angles.

Front

What is the relationship between ∠3 and ∠7 if they are corresponding angles?

Back

If ∠3 and ∠7 are corresponding angles, then they are equal in measure.

Front

How can you identify corresponding angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the measure of corresponding angles if one angle measures 50 degrees?

Back

The corresponding angle will also measure 50 degrees.

Front

If ∠4 is 120 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle will also be 120 degrees.

Front

Which angles are not corresponding angles: ∠1 and ∠5, ∠2 and ∠8, ∠3 and ∠6?

Back

∠2 and ∠8 are not corresponding angles.

Front

What is the transversal in the context of corresponding angles?

Back

A transversal is a line that intersects two or more lines at different points.

Front

If two angles are corresponding angles, what can be inferred about the lines they are on?

Back

The lines are parallel.
