Segments Formed by Chords Secants and Tangents

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

• secant

• sector

• segment

• tangent

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

• internal secant segment

• secant segment

• tangent 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

If two chords intersect each other inside a circle, then the products of their segments are equal. What theorem corresponds to this statement?

• Radius-Tangent

• Intersecting Chords/Two-Intersecting Chords

• Perpendicular Chords

• Secant-Tangent

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment. Which of the following theorem corresponds to the statement?

• Radius-Tangent

• Intersecting Chords/Two-Intersecting Chords

• Intersecting Secants/Secant-Secant

• Intersecting Secant-Tangent

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

The region bounded by an arc and its chord.

• Arc Length

• Segment of a circle

• Sector of a circle

• Tangent

A line segment whose endpoints intersects a circle at exactly two points.

• tangent line

• secant line

• chord

• sector

Which of the following statement is true?

• If a secant and a tangent intersect in the exterior of a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

• If a secant and a tangent intersect in the exterior of a circle, then the measure of the angle formed is one-half the positive sum of the measures of the intercepted arcs.

• If a secant and a tangent intersect in the exterior of a circle, then the measure of the angle formed is the positive difference of the measures of the intercepted arcs.

• If a secant and a tangent intersect in the exterior of a circle, then the measure of the angle formed is the sum of the measures of the intercepted arcs.
