Inscribed and central angles practice

Front

What is a chord in a circle?

Back

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

Front

What is a secant?

Back

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

Front

What is a tangent?

Back

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

Front

What is the diameter of a circle?

Back

The diameter is a chord that passes through the center of the circle, measuring twice the radius.

Front

What is the radius of a circle?

Back

The radius is the distance from the center of the circle to any point on the circle.

Front

What is the circumference of a circle?

Back

The circumference is the distance around the circle, calculated as C = 2πr, where r is the radius.

Front

What is an inscribed angle?

Back

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.

Front

What is a central angle?

Back

A central angle is an angle whose vertex is at the center of the circle and whose sides are radii.

Front

How do you find the measure of an inscribed angle?

Back

The measure of an inscribed angle is half the measure of the intercepted arc.

Front

What is the relationship between a central angle and its intercepted arc?

Back

The measure of a central angle is equal to the measure of its intercepted arc.
