Perpendicular Bisectors and Slopes

The video tutorial from MooMooMath introduces the Perpendicular Bisector Theorem, explaining the concept of perpendicular bisectors and their properties. It demonstrates how points on a perpendicular bisector are equidistant from the segment's endpoints, leading to congruent triangles. The video applies the theorem through diagrams and algebraic problems, showing how to solve for unknowns. It concludes with finding the equation of a perpendicular bisector using midpoint and slope calculations.

What does it mean for two lines to be perpendicular?

• They are parallel to each other.

• They form an acute angle.

• They intersect at a right angle.

• They never intersect.
