Vertical and Adjacent Angles

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

How can you identify vertical angles in a diagram?

Back

Vertical angles can be identified as the pairs of angles that are opposite each other at the intersection of two lines.

Front

How can you identify adjacent angles in a diagram?

Back

Adjacent angles can be identified as angles that are next to each other, sharing a common side and vertex.

Front

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

Back

If two angles are vertical, their measures are equal.

Front

If angle A measures 30 degrees, what is the measure of its vertical angle?

Back

The measure of its vertical angle is also 30 degrees.

Front

If angle A and angle B are adjacent and angle A measures 50 degrees, what is the relationship between angle A and angle B?

Back

Angle A and angle B are supplementary if they form a linear pair, meaning their measures add up to 180 degrees.

Front

What is the sum of the measures of two adjacent angles that form a straight line?

Back

The sum of the measures of two adjacent angles that form a straight line is 180 degrees.

Front

Can two angles be both adjacent and vertical?

Back

No, two angles cannot be both adjacent and vertical at the same time.

Front

What is the formula to find the measure of an angle if you know the measure of its adjacent angle?

Back

If the two angles are adjacent and form a linear pair, you can use the formula: Measure of angle A + Measure of angle B = 180 degrees.
