Identifying Chords Secants and Tangents

If a line segment in drawn from the center of a circle onto a chord, what happens with the chord?

• The chord disappears.

• The chord is bisected.

• The angles are 90 degrees.

• The line from the center is perpendicular to the chord.

Name the tangent line.

• line s

• WR

• VT

• QR

Which answer below is a chord in the circle?

Which line is a secant?

A tangent intersects a circle:

• at only one point

• at two points

• at many points

• at the center

What is the definition of a tangent?

• A line that intersects the circle on two points.

• A line that passes through the center of the circle.

• A line segment that passes through the center of the circle.

• A line that intersects the circle on only one point.

Name a secant of the circle.

A line segment on the interior of a circle with endpoints on the circle

• Radius

• Diameter

• Secant

• Chord
