Perpendicular Bisector Theorem Concepts

The video tutorial covers the perpendicular bisector theorem, explaining that a point on the perpendicular bisector of a segment is equidistant from the segment's endpoints. The video provides a detailed proof using a two-column format, demonstrating congruence through side-angle-side congruence. The proof strategy involves identifying congruent segments and angles, and using the reflexive property to establish triangle congruence, ultimately proving the theorem.

What is the main idea of the perpendicular bisector theorem?

• A point on the bisector is closer to one endpoint.

• A point on the bisector is not related to the endpoints.

• A point on the bisector is equidistant from the endpoints.

• A point on the bisector is farther from the endpoints.
