Inscribed angles and central angles

Front

What is Pi?

Back

Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter.

Front

How is Pi calculated?

Back

Pi is calculated by dividing the circumference of a circle by its diameter.

Front

What is the measure of an arc in a circle?

Back

The measure of an arc is equal to the measure of its corresponding central angle.

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 that extend to the circle.

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 the relationship between an inscribed angle and its intercepted arc?

Back

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

Front

If the measure of a central angle is 90 degrees, what is the measure of the corresponding arc?

Back

The measure of the corresponding arc is also 90 degrees.

Front

If the measure of an inscribed angle is 45 degrees, what is the measure of the intercepted arc?

Back

The measure of the intercepted arc is 90 degrees.
