Circle Geometry Terms

Front

The set of all points in a plane that are equidistant from a given point.

Back

Circle

Front

A segment whose endpoints are the center and any point on the circle.

Back

Radius

Front

The center of the circle is labeled as S.

Back

S is the point from which all points on the circle are equidistant.

Front

The chord of the circle is labeled as segment EH.

Back

A chord is a line segment with both endpoints on the circle.

Front

Line PR is best described as a tangent.

Back

A tangent is a line that touches a circle at exactly one point.

Front

Line MN is best described as a secant.

Back

A secant is a line that intersects a circle at two points.

Front

Line PQ is best described as a chord.

Back

A chord is a line segment whose endpoints lie on the circle.

Front

Line QO is best described as a radius.

Back

A radius is a line segment from the center of the circle to a point on the circle.

Front

Line QP is best described as a chord.

Back

A chord is a line segment whose endpoints lie on the circle.

Front

Line OR is best described as a radius.

Back

A radius is a line segment from the center of the circle to a point on the circle.
