Angle Relationship Review

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal in measure.

Front

What are Vertical Angles?

Back

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

Front

What are Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are Alternate Interior Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

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

Front

What are Same-Side Interior Angles?

Back

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

Front

If angle 2 is 125 degrees, what is the measure of angle 6?

Back

125 degrees.

Front

Solve for x if 2x + 4 = 68.

Back

x = 32.

Front

Identify a pair of alternate interior angles from the following: ∠3 and ∠6, ∠4 and ∠6, ∠3 and ∠7, ∠5 and ∠6.

Back

∠3 and ∠6.

Front

What is the relationship between same-side interior angles?

Back

Same-side interior angles are supplementary, meaning their measures add up to 180 degrees.
