Given two congruent arcs determine the value of your central angle

The video tutorial covers the concept of congruent chords in circles, explaining that chords of equal length have congruent arcs. It further discusses the relationship between central angles and arc measurements, emphasizing that the central angle is equal to the arc's measure. The tutorial concludes with an application of these concepts to solve for a central angle, demonstrating that if an arc measures 67 degrees, the central angle is also 67 degrees.

What is the relationship between congruent chords and their arcs?

• Congruent chords have no relation to arcs.

• Congruent chords have arcs that are twice as long.

• Congruent chords have congruent arcs.

• Congruent chords have different arcs.

What is the central angle equal to in a circle?

• Half of the arc measurement

• Twice the arc measurement

• The same as the arc measurement

• Unrelated to the arc measurement

If an angle is formed with the same endpoints as a central angle, what is its measurement?

• Twice the central angle

• Unrelated to the central angle

• Half of the central angle

• Equal to the central angle

If an arc measures 67 degrees, what is the measure of the central angle?

• Cannot be determined

• 33.5 degrees

• 134 degrees

• 67 degrees

What was the main focus of the lesson on page 129?

• Congruent chords

• Angles with the same endpoints

• Triangle properties

• Central angles and their arcs
