Foundations of Geometry (2)

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 is the sum of complementary angles?

Back

The sum of complementary angles is 90 degrees.

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

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

Back

Vertical angles are equal in measure.

Front

Solve for x: 2x + 5 = 47

Back

x = 21

Front

Solve for x: 3x - 9 = 0

Back

x = 3

Front

What is the definition of adjacent angles?

Back

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

Front

If angle A and angle B are complementary, and angle A measures 30 degrees, what is the measure of angle B?

Back

Angle B measures 60 degrees.

Front

What is the relationship between angles that are supplementary?

Back

Supplementary angles add up to 180 degrees.

Front

Solve for x: 5x = 100

Back

x = 20
