Circles: Lesson 2 Arcs & Chords

In a circle (or congruent circles), the measure of an arc is:

• equal to half of the measure of its corresponding central angle
• equal to the measure of its corresponding central angle
• equal to the measure of its circle's radii
• only calculated by taking the square root of dragon taxis

In a circle (or congruent circles), congruent central angles:

• have congruent chords
• have congruent points
• have similar names
• trunkbuster

In a circle (or congruent circles), congruent central angles:

• are 60 degrees
• have congruent points
• have congruent arcs
• spell out the word "dracula"

In a circle (or congruent circles), congruent arcs:

• have congruent chords
• have congruent points
• are twice the measure of their radii
• can climb a hippo

In a circle (or congruent circles), chords that are the same distance from the center:

• are similar
• have the same name
• are congruent to each other
• are walking dead

If Circle M is congruent to Circle O, then:

• all of their central angles must be congruent
• both circles have centers named "P"
• both circles have congruent radii
• both circles have X-Box Ones

A line segment on the interior of a circle with endpoints on the circle

• Radius
• Diameter
• Secant
• Chord

A ____ angle is an angle whose vertex is a the center of a circle.

• supplementary
• complimentary
• central
• obtuse

An ____ is an unbroken part of a circle consisting of two points called the endpoints and all the points on the circle between them. 

• adjacent
• arc
• algorithm
• area

If the endpoints of an arc lie on a diameter, the arc is a ....

• major
• minor
• semicircle
• sector
