Front

What is the definition of intersecting chords in geometry?

Back

Intersecting chords are two lines that cross each other inside a circle, creating angles and segments.

Front

What is the formula for finding the measure of an angle formed by two intersecting lines?

Back

The measure of the angle is equal to the average of the measures of the opposite angles.

Front

What is the relationship between angles formed by parallel lines and a transversal?

Back

Angles formed by parallel lines and a transversal are either corresponding, alternate interior, or same-side interior.

Front

What is the definition of a circle's radius?

Back

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

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius.
