Given the intersection of two chords not at the center find the measure of an arc

The video tutorial explains how to calculate the measure of angle 5 using geometric principles. It begins by introducing angle 5 and discussing the rules for identifying arcs within a circle. The tutorial then explains the formula for calculating interior angles and demonstrates how to find angle 4. It highlights the relationship between angles 4 and 5 as a linear pair, which adds up to 180 degrees. Finally, the tutorial calculates angle 5 by subtracting angle 4 from 180 degrees.

What is the formula for calculating the measure of an interior angle using arcs?

• 1/2 the difference of the arcs

• 1/2 the sum of the arcs

• The product of the arcs

• The sum of the arcs

How do you calculate the measure of an angle when the point is outside the circle?

• By multiplying the arcs

• By subtracting the smaller arc from the larger arc

• By adding the arcs

• By dividing the arcs

What is the relationship between angles 4 and 5?

• They are vertical angles

• They are complementary angles

• They are supplementary angles

• They are linear pairs

If angle 4 is 58 degrees, what is the measure of angle 5?

• 122 degrees

• 116 degrees

• 66 degrees

What is the sum of angles in a linear pair?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees
