Angles Review

Front

What are vertical angles?

Back

Vertical angles are pairs of opposite angles formed when two lines intersect. They are always congruent (equal in measure).

Front

What is the sum of supplementary angles?

Back

Supplementary angles always add up to 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

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 same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two parallel lines and on the same side of a transversal. They are supplementary.

Front

What is a transversal?

Back

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

Front

If angle 4 is 50 degrees, what is the measure of angle 2 if they are corresponding angles?

Back

Angle 2 is also 50 degrees because corresponding angles are equal.

Front

If angle 1 is 70 degrees, what is the measure of angle 5 if they are alternate interior angles?

Back

Angle 5 is also 70 degrees because alternate interior angles are equal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always congruent (equal in measure).

Front

If angle 3 is 110 degrees, what is the measure of angle 7 if they are vertical angles?

Back

Angle 7 is also 110 degrees because vertical angles are equal.
