Vertical and Adjacent Angles Test

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 adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

If two angles are vertical, what can we say about their measures?

Back

If two angles are vertical, their measures are equal.

Front

If two angles are adjacent, what can we say about their measures?

Back

Adjacent angles can be of any measure; they are not necessarily equal.

Front

What is the sum of the measures of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What is the value of x if ∠A and ∠B are vertical angles and ∠A = 25°?

Back

x = 25°.

Front

What is the value of x if ∠C and ∠D are adjacent angles and ∠C = 45°?

Back

x = 135°.

Front

Name the vertical angle to ∠h if ∠h is formed by two intersecting lines.

Back

The vertical angle to ∠h is the angle that is opposite to it at the intersection.

Front

If ∠E and ∠F are supplementary and ∠E = 70°, what is ∠F?

Back

∠F = 110°.
