Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

If B is the midpoint of AC, what is the relationship between AB and BC?

Back

AB = BC; they are equal in length.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What are complementary angles?

Back

Complementary angles are two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are equal.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

If two angles are supplementary and one angle is 70 degrees, what is the other angle?

Back

The other angle is 110 degrees.

Front

If two angles are complementary and one angle is 40 degrees, what is the other angle?

Back

The other angle is 50 degrees.
