Perpendicular Bisector and Angle Bisector Theorem

Front

What is the Perpendicular Bisector Theorem?

Back

The Perpendicular Bisector Theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

What is the Angle Bisector Theorem?

Back

The Angle Bisector Theorem states that if a point is on the angle bisector of an angle, then it is equidistant from the two sides of the angle.

How do you find the measure of an angle using the Angle Bisector Theorem?

Back

To find the measure of an angle using the Angle Bisector Theorem, you can set up a proportion based on the lengths of the segments created by the angle bisector.

What does it mean for a line to be a perpendicular bisector?

Back

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

Front

If a point lies on the perpendicular bisector of a segment, what can you say about its distances to the endpoints?

Back

The distances from the point to the endpoints of the segment are equal.

If two angles are bisected, what can you say about the measures of the resulting angles?

Back

The measures of the resulting angles are equal to half of the measure of the original angle.

Front

What is the significance of the point where the perpendicular bisector intersects a segment?

Back

The intersection point is the midpoint of the segment, and it is equidistant from both endpoints.
