Chord Central Angles Conjecture
|
If two chords in a circle are congruent, then they determine two central angles that are congruent.
|
|
Chord Arcs Conjecture
|
If two chords in a circle are congruent, then their intercepted arcs are congruent.
|
|
Perpendicular to a Chord Conjecture
|
The perpendicular from the center of a circle to a chord is the perpendicular bisector of the chord.
|
|
Chord Distance to Center Conjecture
|
Two congruent chords in a circle are equally distant from the center of the circle.
|
|
Perpendicular Bisector of a Chord Conjecture
|
The perpendicular bisector of a chord passes through the center of the circle.
|
|
Tangent Conjecture
|
A tangent to a circle is perpendicular to the radius drawn to the point of tangency.
|
|
Tangent Segments Conjecture
|
Tangent segments to a circle from a point outside the circle are congruent.
|
|
Inscribed Angle Conjecture
|
The measure of an inscribed angle in a circle is half the measure of the arc it intercepts.
|
|
Inscribed Angles Intercepting Arcs Conjecture
|
Inscribed angles that intercept the same arc are congruent.
|
|
Angles Inscribed in a Semicircle Conjecture
|
Angles inscribed in a semicircle are right angles.
|
|
Cyclic Quadrilateral Conjecture
|
The opposite angles of a quadrilateral inscribed in a circle are supplementary.
|
|
Parallel Lines Intercepted Arcs Conjecture
|
Parallel lines intercept congruent arcs on a circle.
|
|
Arc Length Conjecture
|
The length of an arc equals the degree measure of the arc divided by 360 degrees, times the circumference of the circle.
|
|
NOTE
|
I did not include the conjecture about the circumference!!! That is just common knowledge.
