Circle Facts

Question 1

Equal chords are equidistant from the center of the circle

Question 2

All diameters of a circle are congruent

Question 3

A radius or diameter that bisects a chord is perpendicular to that chord

Answer 3

The perpendicular bisector of a chord contains the center of the circle

Question 4

Chord and tangent is 1/2 it’s intercepted arc, radii and tangent meet at a right angle

Answer 4

Chord-tangent vs chord-radii

Question 5

How to solve bisector

Answer 5

1. <3 = <4
   Angle 3 plus angle 4 = <FAD
   2(<3) = <FAD, 2(<4) = <FAD substitution axiom
   3) <3 (1/2 FAD) <4 (1/2 Fad)
   4( FAD bisects blah blah blah
