Geometry A Unit 2 Review

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

Identify the corresponding angles when lines c and d are parallel.

Back

∠15 and ∠11.

Front

What are alternate exterior angles?

Back

Angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

Identify the alternate exterior angles when lines c and d are parallel.

Back

∠3 and ∠10.

Front

What are alternate interior angles?

Back

Angles that lie between the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

Identify the alternate interior angles when lines c and d are parallel.

Back

∠8 and ∠13.

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

If ∠1 ≌ ∠3, what can be concluded about lines w and x?

Back

Lines w and x are parallel by the Corresponding Angles Postulate.

Front

What are consecutive interior angles?

Back

Angles that lie between the two parallel lines and on the same side of the transversal. They are supplementary.

Front

If two lines are cut by a transversal and the consecutive interior angles are supplementary, what can be concluded?

Back

The two lines are parallel.
