Angles, a la Shmoop When two old friends bump into each other,

00:10

it’s called a “reunion.” Or, if they really don’t like each other

00:15

anymore, it’s called “awkward.” But when two lines bump into each other, the

00:19

space where those lines meet is called an angle.

00:23

If that angle is less than ninety degrees, it is an acute angle.

00:27

That’s “acute angle” with an “A” at the beginning,

00:32

These angles have less than ninety degrees, and it’s one of the five different types

00:36

of angles… …or six if you count pro wrestler Kurt Angle.

00:37

In fact, we’re a little nervous about not counting him.

00:37

A right angle is an angle that’s exactly ninety degrees…

00:41

…which means it is formed when two straight lines meet in a perpendicular fashion…

00:48

…or when some yoga master bends in a really zany way.

00:54

An obtuse angle is an angle that is between ninety and one hundred and eighty degrees.

01:00

A reflex angle is an angle greater than one hundred and eighty degrees, which makes it

01:06

the greatest of all angles. Not that it needs a bigger head.

01:13

The final type of angle hides in plain sight – it’s sorta the chameleon of the angle

01:17

world. Take a gander at this image, and tell us where

01:21

the angle is. We’re waiting. You give? It’s right here.

01:27

It might look like a plain old line, but it’s technically a “straight angle.”

01:32

Be careful when handling one – those straight edges will getcha.

01:36

A straight angle can only be exactly one hundred and eighty degrees…

01:40

…or, in other words, what we call “a line” here at Shmoop.

01:45

So why do you need to know all these guys? Knowledge of angles can help you get dozens

01:49

of awesome jobs in fields such as engineering, construction, real estate, and architecture.

01:58

It will also help you build the most technically perfect paper footballs.
