Radius, Diameter, Chords, Tangent

What is Line RY?

• Tangent

• chord

• Radius

• Diameter

What is segment QR?

• tangents

• chord

• secant

• radius

What is MP?

• Center

• Radius

• Diameter

• Chord

an angle with a vertex on the circle, and two sides that are chords

• central angle

• inscribed angle

• minor angle

• major angle

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

• obtuse

• straight

A(n) _____ to a circle is a line, ray or segment in the plane of the circle that intersects the circle in exactly one point.

• tangent

• secant

• radius

• arc
