Chap 10 Quiz Geometr
| Question | Answer |
|---|---|
| tangent | a line in the plane of a circle that intersects the circle in exactly one point. |
| 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 |
| equidistant chords | in the same circle or congruent circlestwo chords are congruent if and only if they are equidistant to the center of the circle |
