Circles Angles Arcs and Chords

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

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, the perpendicular bisector of a chord:

• is tangent to the circle

• is the diameter

• is a right triangle

• eats frosted flakes for dinner

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

In circle O, the radius is 4, and the measure of minor arc AB is 120 degrees. Find the length of minor arc AB.

• 5/3π

• 9π

• 7/4π

• 7/2π

• 1/8π

When she is outdoors, Tasha, the dog, is tied to a stake in the center of a circular area of radius 24 feet. The angle between her dog house and her favorite hydrant is 165 degrees.  What is the length of the arc from her dog house to the hydrant, following minor arc DG.

• 40π feet

• 35π feet

• 11π feet

• 22π feet

In circle O, the radius is 4, and the length of minor arc AB is 4.2 feet.  Find the measure of minor arc AB to the nearest degree.
