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
