Assessment 2 - Angle Relationships

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

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal crosses parallel lines, it creates several pairs of angles that have specific relationships, such as corresponding angles, alternate interior angles, and alternate exterior angles.

Front

If m∠3 = 145°, what is m∠5 if ∠3 and ∠5 are corresponding angles?

Back

m∠5 = 145° because corresponding angles are equal.

Front

If m∠1 = 122°, what is m∠4 if ∠1 and ∠4 are vertical angles?

Back

m∠4 = 122° because vertical angles are equal.

Front

If m∠1 = 122°, what is m∠8 if ∠1 and ∠8 are alternate exterior angles?

Back

m∠8 = 122° because alternate exterior angles are equal.

Front

If m∠2 = 137°, what is m∠6 if ∠2 and ∠6 are corresponding angles?

Back

m∠6 = 137° because corresponding angles are equal.

Front

What is the sum of the measures of complementary angles?

Back

The sum of the measures of complementary angles is 90 degrees.
