Chords and Tangent Circle

In the diagram, TP and TQ are tangents to circle O. Determine the value of x. (Note the angles with single arcs are not necessarily congruent in this diagram.)

• 70

• 110

• 140

• 90

Solve for x.

• 3.6

• 9.2

• 11.5

• 14.3

Find the value of x.

• 9.8

• 6.3

• 12.6

• 4.9

Name the part shown in the given circle.

• Circumference

• Tangent

• Sector

• Radius

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

An angle is a(n) ______ if the vertex is on a circle and the sides of the angle are shords of the circle.

• right angle

• acute angle

• inscribed angle

• intercepted angle

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

Segments with endpoints on a circle are called _____
