In this clip, we're going to learn the proper way to use a ruler. And how to read a ruler. Number one, if you're going to use a ruler. We'll use this small ruler here. Especially, in Geometry, if you're going to make a straight line. You're going to line up the ruler with your eyes. And put the ruler on the paper. Hold the ruler down. And then, make a straight line. O.k. It's a lot easier. Most people do this. They line up the ruler, like this. And they make a line. That's not the proper way. The proper way is always to keep. Now what if you need to, to do a vertical line. Well, just easy, turn the paper. And then put the ruler down. and make your straight line. Always keep the ruler leveled with your eyes. That is the proper way of using a ruler. Now if you want to use it to measure. Let's say, you want to measure this line, right here. O.k. Here's a big ruler that we have. O.k. We put it at the zero point, right there. There's the zero point. And we see where the line ends. And it ends right here. We got lucky over here. It ends at exactly between the ten and the eleven. So this is ten, so that's ten. And half, so ten and one half inches. Remember your fractions from the other clip on rulers. And you should be able to measure.
