11-3 Arcs and Chords (Flashcardizz)

Front

What is the relationship between the measure of an arc and its corresponding central angle in a circle?

Back

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

Front

What happens to a chord when a diameter is perpendicular to it?

Back

The diameter bisects both the chord and its corresponding arc.

Front

If the measure of a central angle is 80 degrees, what is the measure of the corresponding arc?

Back

The measure of the corresponding arc is also 80 degrees.

Front

What is the formula to find the length of an arc in a circle?

Back

Arc length = (θ/360) * 2πr, where θ is the central angle in degrees and r is the radius.

Front

How do you find the value of x when given two intersecting chords in a circle?

Back

Use the formula: (part 1) * (part 2) = (part 3) * (part 4).

Front

What is a chord in a circle?

Back

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

Front

What is the definition of a diameter in a circle?

Back

A diameter is a chord that passes through the center of the circle.

Front

How do you determine if two arcs are congruent?

Back

Two arcs are congruent if they have the same measure.

Front

What is the relationship between the radius and the chords in a circle?

Back

The perpendicular from the center of the circle to a chord bisects the chord.

Front

What is the measure of a semicircle?

Back

The measure of a semicircle is 180 degrees.
