secant a line that intersects a circle in two points
radius a segment whose endpoints are the center and any point on the circle
chord a segment whose endpoints are on a circle
diameter a chord that contains the center of the circle
common internal tangent goes between the circles
common external tangent goes on the same side of the outside of the circles
point of tangency the point of which a tangent touches a circle
circle with right triangle with radius as one side pythagorean theorem
tangents that meet at one point set equal
semicircle =180*
minor arc <180
major arc >180
an inscribed angle is always - the measure of the intercepted arc 1/2
inscribed angles if two inscribed angles are intercepting the same arc, then they are congruent
inscribed triangles if one side of the triangle is the diameter, it is a right triangle
chords 1. if one chord is the perpendicular bisector of another chord, then it is a diameter 2. if a diameter is perpendicular to another chord, then it bisects the chord
