necessary conditions are met to assure the truth of another statement

perpendicular bisector.

Section 8.3

Theorem 8.3 - Through a given point of a given line there passes a plane perpendicular to the given line.

This is true of theorems 8.3 (auxiliary planes drawn) and 6.1 ( the usefulness of having a line perpendicular to a given line in a plane)... The remainder of the proof is basically contingent on the Basic Theorems on Perpendiculars

Theorem 8.4 - If a line and a plane are perpendicular, then the plane contains every line perpendicular the the given line at its point of intersection with the given plane.

Again, this is contingent on the idea that in a plane, there is only one line perpendicular to a given line (Auxiliary plane used)
