In the same circle or in equal circles, equal chords cut off equal arcs.


In the same circle or in equal circles, equal central angles cut off equal arcs.

Principle 13 - page 295 (MMT)

In the same circle or in equal circles, two central angles have the same ratio

the two segments of the other chord. as the arcs that cut off by the angles.


A line drawn from the center of a circle perpendicular to a chord bisects the

chord and the arc cut off by the chord. The perpendicular bisector of a chord

passes through the center of a circle.



A line perpendicular to a radius at its extremity is tangent to the circle. A tangent

is perpendicular to a radius at its tangent point.


Two tangents drawn to a circle from a point outside the circle are equal. The

angle at the outside point is bisected by a line drawn from the point to the center

of the circle.


If two chords intersect inside a circle, the product of the two segments of one

chord is equal to the product of
