Measuring Angles: Key Concepts and Techniques

What is the first step in measuring angles?

• Use a protractor to measure immediately.

• Identify the type of angle.

• Write down the angle measurement.

• Check if the angle makes sense.

What is the characteristic of an obtuse angle?

• It is less than 90 degrees.

• It is exactly 90 degrees.

• It is more than 90 degrees.

• It is less than 180 degrees.

What is the measure of angle AGD?

• 60 degrees

• 90 degrees

• 120 degrees

• 110 degrees

How do you verify your angle measurement is correct?

• Using estimation to check if it makes sense.

• Asking someone else to measure it.

• Comparing it with a known angle.

• By measuring again with a different tool.

What is the measure of angle AGB?

• 50 degrees

• 110 degrees

• 90 degrees

• 60 degrees

What should you do if an angle does not start at zero on a protractor?

• Guess the measurement.

• Use estimation and different strategies to measure.

• Only use subtraction to find the measure.

• Ignore the angle as it cannot be measured.

How can you measure an angle that's in the middle of a protractor?

• Angles in the middle cannot be measured.

• By estimating and then using hops or subtraction.

• By using only the right zero.

• By using only the left zero.

What is the measure of angle BGD?

• 50 degrees

• 60 degrees

• 40 degrees

How do you find the measure of an unknown angle without a protractor?

• Using given angle measures and mathematical operations.

• Guessing based on the angle type.

• Estimating and not verifying.

• Measuring with a ruler.
