Arc-Chord-Diameter Three theorems with applications / 10.3

10-3 Three theorems and sample problems 10 & 19 from the textbook

This lesson demonstrates the following theorems from the McDougal-Littel high school geometry book:

THEOREM 10.4
If one chord is a perpendicular bisector of another chord, then the first chord is a diameter.

THEOREM 10.5
If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc.

THEOREM 10.6
In the same circle, or in congruent circles, two chords are congruent if and only if they are equidistant from the center.
