How to find the measure of three angles that are supplementary

The video tutorial explains how to find the measures of angles 5 and 6 using known properties of angles. It covers the concept of angles forming a line summing to 180 degrees and introduces the idea that angles can be equal. The tutorial demonstrates solving for angle measures using variables and emphasizes the importance of proper notation when discussing angle measurements.

What is the sum of angles on a straight line?

• 360 degrees

• 180 degrees

• 90 degrees

• 45 degrees

If two angles are equal and add up to 90 degrees, what is the measure of each angle?

• 90 degrees

• 60 degrees

• 45 degrees

• 30 degrees

What is the relationship between angles 5 and 6?

• Angles 5 and 6 are complementary

• Angles 5 and 6 are equal

• Angle 5 is twice angle 6

• Angle 5 is half of angle 6

What is the correct way to express the measurement of angle 5?

• Angle 5 is 45

• 5 equals 45

• Angle 5 = 45

• Measure of angle 5 equals 45 degrees

Why is it important to include 'M' when discussing the measurement of angles?

• To indicate the angle is measured in meters

• To specify the angle is a right angle

• To clarify that the value is a measurement

• To denote the angle is part of a triangle
