Front

What is an inscribed quadrilateral?

Back

An inscribed quadrilateral is a four-sided figure where all vertices lie on the circumference of a circle.

Front

What is the relationship between opposite angles in an inscribed quadrilateral?

Back

The opposite angles of an inscribed quadrilateral are supplementary, meaning they add up to 180 degrees.

Front

Define a major arc in a circle.

Back

A major arc is an arc that is larger than a semicircle, covering more than 180 degrees of the circle.

Front

What is a radius of a circle?

Back

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

Front

What is the formula for the circumference of a circle?

Back

The circumference C of a circle is given by the formula C = 2πr, where r is the radius.

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

What is the difference between a chord and a diameter?

Back

A chord is a line segment with both endpoints on the circle, while a diameter is a special chord that passes through the center of the circle and is the longest chord.

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

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 a semi-circle?

Back

A semi-circle is an arc that represents half of a circle, measuring 180 degrees.
