What is the measure of a major arc in terms of a minor arc

The video tutorial explains the concept of arcs in a circle, focusing on the differences between minor and major arcs. It describes how to label major arcs using three points on the circle and provides a method to calculate the length of a major arc by subtracting the minor arc's value from 360 degrees.

What is the relationship between a central angle and its corresponding minor arc?

• The central angle is equal to the measure of the minor arc.

• The central angle is twice the measure of the minor arc.

• The central angle is unrelated to the minor arc.

• The central angle is half the measure of the minor arc.

How is a major arc different from a minor arc?

• A major arc is smaller than a minor arc.

• A major arc is the same size as a minor arc.

• A major arc is larger and includes the rest of the circle not covered by the minor arc.

• A major arc is unrelated to a minor arc.

Why is it important to use three points when describing a major arc?

• To make the arc look more complex.

• To ensure the arc is longer.

• To clearly distinguish it from a minor arc.

• To make calculations easier.

What is the formula to find the measure of a major arc?

• Add 180 degrees to the minor arc.

• Subtract the minor arc from 180 degrees.

• Add the minor arc to 360 degrees.

• Subtract the minor arc from 360 degrees.

What additional information is usually provided to help label a major arc?

• A fourth point on the circle.

• The radius of the circle.

• A third point on the circle.

• The diameter of the circle.
