Drawing Angles with a Protractor

In this video, Mr. J demonstrates how to draw a 110° angle using a protractor. The process involves drawing the first arm of the angle, aligning the protractor, marking the correct angle measurement, and drawing the second arm by connecting the dots. The video concludes with verifying the accuracy of the drawn angle. This tutorial provides a clear, step-by-step guide to using a protractor for angle construction.

What is the main objective of the video tutorial?

• To draw a 110° angle using a protractor

What should be done after drawing the first arm of the angle?

• Erase the line

• Draw a circle

• Measure the angle

• Mark the vertex with a dot

Where should the center point of the protractor be placed?

• At the midpoint of the line

• At the end of the arm where the dot is

• Anywhere on the line

• At the opposite end of the line

What is the baseline of the protractor used for?

• To mark the midpoint

• To draw a circle

• To align with the arm of the angle

• To measure the length of the line

How do you determine which 110° mark to use on the protractor?

• By choosing the inner track of numbers

• By picking any 110° mark

• By selecting the mark closest to the baseline

• By using the outside track of numbers

Why is it important to use the outside track of numbers on the protractor?

• Because it is more accurate

• Because it is easier to read

• Because it is closer to the center point

• Because the arm aligns with 0° on the outside track

How can you verify that the angle drawn is 110°?

• By using a ruler

• By checking with a compass

• By aligning the protractor again

• By drawing another angle
