Below are sample questions representative of the exercises included on this worksheet and related GEO.115 Circle vocabulary and parts of a circle skill assessments:

Problem 1Difficulty: Mastery
A circle diagram uses four labels: 1 is a segment from center O to the rim, 2 is a straight segment connecting two rim points, 3 is a line touching the circle at exactly one point, and 4 is a curved part of the circle. Which mapping is correct?
A1 radius, 2 chord, 3 tangent, 4 arc
B1 chord, 2 radius, 3 secant, 4 central angle
C1 tangent, 2 arc, 3 radius, 4 chord
D1 central angle, 2 secant, 3 chord, 4 radius
Solution & Explanation:A center-to-rim segment is a radius, a straight segment between rim points is a chord, a line touching once is a tangent, and a curved part is an arc.
Problem 2Difficulty: Mastery
Which statement best proves that line p is a secant of circle O?
ALine p intersects circle O at two distinct points.
BLine p touches circle O at exactly one point.
CLine p begins at the center and ends on the circle.
DLine p follows the circumference between two points.
Solution & Explanation:A secant line intersects a circle at two points. One point would indicate a tangent, not a secant.
Problem 3Difficulty: Mastery
Which statement best proves that line m is tangent to circle O?
ALine m has exactly one point of intersection with circle O.
BLine m has two endpoints on circle O.
CLine m is a curved part of the circumference.
DLine m forms an angle with vertex O.
Solution & Explanation:The defining feature of a tangent line is exactly one point of contact with the circle.
