Flashcards in Ch. 10-10.3 Deck (14):
1

Radius

A segment whose end points are the center and any endpoint on the circle

2

Chord

A segment whose end points are on a circle

3

Diameter

A chord that contains a center

4

Secant

A line that intersects a circle in two points

5

Tangent

The line that intersects the circle in exactly one point

6

Theorem 10.1

In a plane a line is tangent to a circle of and only if the line is perpendicular to a radius of a circle at its end point on the circle

7

Theorem 10.2

Tangent segments from a common external point are congruent

8

Central angle

An angle whose vertex is the center of the circle

9

Minor arc

Two letters
Less than 180

10

Major

Three letters
Greater than 180

11

Theorem 10.3

In the same circle or congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent

12

Theorem 10.4

If one chord if a perpendicular bisector of another chord then the first chord is a diameter

13

Theorem 10.5
