Tangents Chords and Secants Arc Measures

In a circle or in congruent circles, two minor arcs are congruent if and only if their corresponding ___________ are congruent.

• central angle

• inscribed angle

• intercepted arc

• congruent arc

What do you call the line coplanar with the circle and intersects it in exactly two points?

• secant

• sector

• segment

• tangent

Which of the following is a secant segment?

• segment OM

• segment ON

• segment KL

• segment ML

What is the measure of an angle formed by a secant and a tangent that intersects on the circle?

• one-sixth the measure of its intercepted arc

• one-fifth the measure of its intercepted arc

• one-fourth the measure of its intercepted arc

• one-half the measure of its intercepted arc

Which of the following lines refers to a line that is tangent to two circles in the same plane?

• common tangent

• curve

• secant

• tangent

Which of the following terms refers to the region bounded by two radii and the minor arc they determine?

• secant segment

• sector of a circle

• segment of a circle

• tangent segment

A secant segment may be divided into two parts. What do you call the part whose endpoints are on the circle and all its points are in the interior of the circle?

• external secant segment

• internal secant segment

• secant segment

• tangent segment

It is a part of the secant segment whose one endpoint is a point on the circle and the other endpoint is in the exterior of the circle.

• external secant segment

What is the process in finding the measure of an angle formed by secants intersecting inside the circle?

• one-half the sum of the measures of the arc intercepted by the angle and its vertical angle pair

• one-half the sum of the measures of the arc intercepted by the angle and its intercepted arc

• twice the sum of the measures of the arc intercepted by the angle and its vertical angle pair

• twice the sum of the measures of the arc intercepted by the angle and its intercepted arc
