How To: Use a protractor to measure the height of any object
In this video, we learn how to use a protractor to measure the height of any object. First, attach a level to the protractor, followed by a straw at the 45 degree angle. Next, walk back form the object while looking through the straw. Keep walking back until you spot the top of the object through the straw, then measure to the base of the object. After this, you will have an isosceles triangle that has two equal sides. Use these sides to help find what the size of the object is. After this, a...
