Circles Chords and Arcs

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), the measure of an arc is:

• equal to twice the measure of its corresponding inscribed angle
• equal to the measure of its corresponding inscribed angle
• equal to half of the measure of its corresponding inscribed angle
• equal to four cups of wheat flour

In a circle, if a diameter is is perpendicular to a chord, then:

• it bisects the chord
• it bisects the corresponding arc
• it bisects BOTH the chord and its arc
• none of these answers are correct

In a circle, if a diameter bisects a chord (that is not a diameter), then:

• it is a secant
• it is parallel to the chord
• it is perpendicular to the chord
• it is just shaking out the sillies

The radius of a circle is

• The measurement from the center of a circle to an edge of the circle.
• The measurement around the circle
• The measurement from and edge of the circle to another edge through the center
• A line perpendicular to the diameter of the circle

A tangent line intersecting with a radius always creates a ____________ angle

• right
• acute
