Perpendicular and Angle Bisectors

Front

What is a perpendicular bisector?

Back

A line that divides a segment into two equal parts at a 90-degree angle.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

Define angle bisector.

Back

A ray that divides an angle into two equal angles.

Front

What is the relationship between a point on the angle bisector and the sides of the angle?

Back

A point on the angle bisector is equidistant from the two sides of the angle.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of their measures is 90 degrees.

Front

What is the measure of a right angle?
