Measuring angles using a simple tool


You hopefully printed the circle divided into 4 equal pieces? Cut this out and fold it in half, then in half again. You have just created a right angle measuring tool. Take a few minutes, find some examples of angles around you, and measure them. This is just a very rough measurement.


 * Is the angle LESS than a right angle?
 * Is the angle EQUAL to a right angle?
 * Is the angle MORE than a right angle?

Try this yourself first.

I created a photo album with some pictures of me going through the process. I've made comments on the photos where I've measured. You can view these comments for my "answers"
