Intercepted Arc

the part of the circle between the points of intersection when the central angle intersects the circle

Steps on how to graph

1) determine end behavior 2) find the zeros 3) use table of values to determine points 4) plot points 5) draw graph

Chord

A segment whose endpoints are on a circle

Major Arc

An arc of a circle whose measure is greater than 180 degrees.

Minor Arc

An arc of a circle whose measure is less than 180 degrees.

Chord Theorem 3-2

If a radius bisects a chord, then it is perpendicular to the chord

Chord Theorem 3-1

If a radius is perpendicular to a chord, then it bisects the chord.

Chord Theorem 3-3

In a circle, if two chords have the same distance from the center, then the chords are congruent

Radius

The distance from the center of a circle to any point on the circle

Graph

a geometric representation of a function

Central Angle

an angle whose vertex is the center of the circle

EVEN & NEGATIVE

both down

EVEN & POSITIVE

both up

Arc

consists of two points and all the other points in between the two given points

ODD & POSITIVE

down left, up right

Polynomial Function

is a function involving only non-negative integer powers of x.

Circle

measures 360 degrees

Circles

set of points in a plane that is equidistant to a fixed point called the center

Naming and Measuring Arcs

the arc measure is the degree measure of the central angle that intersects the arc

Leading Coefficient of a Polynomial

the coefficient of the leading term

Semi Circle

the half of a circle; 180 degrees

Degree of a Polynomial

the highest exponent or power in the polynomial

Intercepted Arc

the measure of the intercepted arc is equal to the measure of the central angle

Leading Term of a Polynomial

the term with the highest power of x

Constant of a Polynomial

the term without a degree/exponent

ODD & NEGATIVE

up left, down right

Diameter

a chord that passes through the center of the circle
