How do you figure out the degree of a shape using a protractor?
You can find out the degrees of the angles of shape shape by
following these instructions.
First you line up the bottom line of the protractor onto a side
of a shape. The corner of the shape should be on the tiny dotlike
thing in the middle of the bottom line of the protractor. Next, you
find out if the angle is obtuse (larger than a right angle), acute
(smaller than a right angle), or right.
If it's obtuse, you know that it's larger than 90 degrees. You
should look at the larger number the other line is pointing at.
If it's acute, find you the angle by finding out which number
the other line is pointing at.
If you think it's a right angle, see if the line's pointing at
another number. Otherwise, it's a right angle.
