What is the measure of minor arc SN if it is given as 65 degrees?

Back

The measure of minor arc SN is 65 degrees.

Front

Define a circle.

Back

A circle is a set of points in a plane that are equidistant from a fixed point called the center.

Front

What is the formula for the circumference of a circle?

Back

The circumference \( C \) of a circle is given by \( C = 2\pi r \), where \( r \) is the radius.

Front

What is the relationship between the radius and diameter of a circle?

Back

The diameter is twice the length of the radius: \( d = 2r \).

Front

What is a secant in relation to a circle?

Back

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

Front

What is the definition of a tangent to a circle?

Back

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