Plane Angle for Dummies
noun
pronunciation: pleɪn_'æŋɡəlWhat does Plane Angle really mean?
Plane angle is a term that is used in mathematics to describe the measure of the amount of rotation between two lines in a plane that share a common vertex or endpoint. Okay, before we go any further, let's break that down a little bit. Imagine you have two lines on a piece of paper, and they meet or intersect at one point. That point where the lines meet is called the vertex.
Now, picture this - you take one line and rotate it around the vertex until it aligns with the other line. The amount of rotation you made is what we call a plane angle. It's like twisting or turning one line to match up with the other line. You can think of it as the "twistiness" or the "bendiness" between those two lines.
But wait, there's more! Just like there can be different sizes of angles, there can also be different types of plane angles. The type of plane angle depends on the measurement of the rotation. If the rotation is less than 90 degrees, it's called an acute angle. You can think of it as a small twist or a narrow V-shape. If the rotation is exactly 90 degrees, it's called a right angle. Imagine the corner of a square - that's a right angle.
Now, if the rotation is more than 90 degrees but less than 180 degrees, it's called an obtuse angle. Picture a wider twist or a big open V-shape. And finally, if the rotation is exactly 180 degrees, it's called a straight angle. Now, this might be a bit trickier to imagine, but think of a line that is completely straight, like the horizon. That's a straight angle.
So, in summary, a plane angle is the amount of rotation or twist between two lines in a plane, measured from the vertex or the point where the lines meet. It can be classified into different types - acute, right, obtuse, or straight - depending on the measurement of the rotation. So, whenever you see two lines meeting and want to know how much they've twisted, just think about plane angles!
