What grade level is the concept of measuring angles discussed in the video?

• Third Grade

• Fourth Grade

• Sixth Grade

• Fifth Grade

What is the state standard mentioned for measuring angles?

• 4.7 C

• 4.7 B

• 4.7 D

• 4.7 A

What tool is used to measure the angle in the video?

• Ruler

• Compass

• Protractor

• Calculator

What should be done if the rays of the angle do not align with zero on the protractor?

• Guess the angle

• Use the highest number

• Add the two readings

• Subtract the two readings

What is the correct way to measure an angle using a protractor when the rays are not on zero?

• Subtract the smaller number from the larger

• Multiply the numbers

• None of the above

• Add the numbers where the rays fall

What is the measure of angle T if one ray is at 150 and the other at 30?

• 150 degrees

• 30 degrees

• 120 degrees

• 180 degrees

What is the total degrees in a straight angle as mentioned in the video?

• 90 degrees

• 180 degrees

• 360 degrees

• 270 degrees

Why is it incorrect to say the angle is 150 degrees if one ray is at 150 and the other is not on zero?

• Because addition is needed

• None of the above

• Because subtraction is needed

• Because it should be 180 degrees

Which option describes the correct answer for the angle measurement in the video?

• 60 degrees

• 120 degrees

• 30 degrees

• 150 degrees

What mistake do students often make when using a protractor as described in the video?

• Placing the protractor upside down

• Adding the numbers instead of subtracting

• Ignoring the zero alignment

• All of the above
