Measuring Angles and Angle Types

The video tutorial explains how to use a protractor to measure angles, focusing on angles BOD and COD. It demonstrates the process of reading angles in degrees and solving equations to find unknown angles. The tutorial also covers the characteristics of acute angles and briefly mentions obtuse angles.

What tool is commonly used to measure angles?

• Calculator

• Protractor

• Compass

• Ruler

What is the first step in measuring an angle with a protractor?

• Use a calculator

• Estimate the angle

• Draw a line

• Align the protractor with the angle's vertex

How is the measure of angle BOD denoted?

• BOD

• m∠BOD

• BOD°

• ∠BOD

What is the measure of angle BOD?

• 60 degrees

• 75 degrees

• 65 degrees

• 70 degrees

What type of angle is angle BOD?

• Straight angle

• Right angle

• Obtuse angle

• Acute angle

What is the next angle to measure after BOD?

• Angle DOB

• Angle COD

• Angle AOD

• Angle COB

How do you find the measure of angle COD?

• By dividing angles

• By adding angles

• By subtracting angles

• By multiplying angles

What is the measure of angle COB?

• 120 degrees

• 130 degrees
