Geometry proofs

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

What is the Segment Addition Postulate?

Back

The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

Front

What must be shown to prove that two angles are supplementary?

Back

To prove that two angles are supplementary, you must show that their measures add up to 180 degrees.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What can be concluded if two angles are supplementary?

Back

If two angles are supplementary, then the sum of their measures equals 180 degrees.

Front

What is a segment bisector?

Back

A segment bisector is a point, line, ray, or segment that divides another segment into two equal parts.

Front

What is the definition of a midpoint?

Back

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

Front

How can you identify the midpoint of a segment?

Back

The midpoint of a segment can be identified as the point that is equidistant from both endpoints of the segment.

Front

What is the relationship between a segment bisector and the midpoint?

Back

A segment bisector intersects the segment at its midpoint, creating two equal segments.

Front

What is the measure of an angle?

Back

The measure of an angle is the amount of rotation needed to bring one ray into alignment with another ray, typically measured in degrees.
