when your using an angle ruler, otherwise known as the protractor, you start by lining up the line (located at hte center of the bottom area) with the point of the angle where the two lines of it meet. then you you line up the line with whatever number it would continue onto.
example: L is a 90 degree angle. if u lined up the part of it pointing upward with a number on the curved part of the protractor, it would point directly at 90.
My daughter in 5th grade would like me to mention that she answered this question, and i typed it here. she also gave the example.

What is used to draw right angles?
I generally use a pencil and ruler. To construct the right angle to draw it I also use compasses. To measure the right angle to draw it I also use a protractor.
What can you use to measure angles other than a protractor?
A ruler. Add a line to make the angle into a triangle, measure the sides and use trigonometry.
How do you bisect an angle using a ruler or double straightedge?
create a 'v' parralel to the 'v' of your angle using the width of your ruler, join the two apexes and continue the line to biscect the angle.

How do measure an angle with a ruler?
You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.
How do you angle a picture on pages?
You angle a picture on pages by turning it a little bit but not to much or you will get a obtuse angle and make sure you use a ruler or something straight to balance it.
