Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

Identify a chord in a circle.

Back

Front

What is a tangent to a circle?

Back

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

Front

How do you calculate the measure of an arc in a circle?

Back

The measure of an arc can be calculated using the central angle that subtends the arc. The measure of the arc is equal to the measure of the central angle.

Front

What is the relationship between the angles formed by two intersecting chords?

Back

The angles formed by two intersecting chords are related such that the measure of each angle is equal to half the sum of the measures of the arcs intercepted by the angle.

Front

What is the formula for the length of an arc?

Back

Front

What is the measure of a semicircle?

Back

The measure of a semicircle is 180 degrees.

Front

Define a secant line in relation to a circle.

Back

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

Front

What is the difference between a chord and a diameter?

Back

A diameter is a special type of chord that passes through the center of the circle and is the longest chord.

Front

How do you find the measure of an angle formed by two tangents to a circle?

Back

The measure of the angle formed by two tangents to a circle is equal to half the difference of the measures of the intercepted arcs.
