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 Triangle Angle Bisector Theorem?

Back

The Triangle Angle Bisector Theorem states that the ratio of the lengths of the two segments created by an angle bisector on the opposite side is equal to the ratio of the lengths of the other two sides of the triangle.

What is a Perpendicular Bisector?

Back

A Perpendicular Bisector is a segment, line, or ray that intersects another segment at its midpoint and forms a right angle (90 degrees) with it.
