Think you know everything about angles? [Boy wearing an angle expert shirt]
- 00:15
Sure, you can spot an obtuse angle right away – they’re the big guys. [Obtuse angle appears]
- 00:19
And acute angles?
- 00:20
Pffffft.
- 00:21
You'd recognize those lil' guys anywhere.

Hey, you even know how to take their exact measurements! [Protractor flies into the boys hand]
- 00:27
You're a regular angle expert, right?
- 00:30
But…uh-oh.
- 00:31
What's that?
- 00:32
There, lurking in that dark corner… [Torch light searching around a dark room]
- 00:34
….there are other angles living among us…
- 00:36
…and they really could use a light bulb, or a candle or something…seriously, why [Other angles hiding in the dark room]
- 00:41
are they sitting in the dark?
- 00:43
Anyway.
- 00:44
Take this angle.
- 00:45
Sure, it looks like a straight line, but it’s actually an angle in disguise. [Straight line with eyes]
- 00:48
Yep – a straight line has an angle measurement, too.
- 00:51
Check it out.
- 00:52
It measures exactly 180-degrees. [Protractor on the line]
- 00:54
It’s twice the size of a right angle…
- 00:57
...and we call this one a “straight angle.”
- 00:59
But wait, there’s more!
- 01:01
Man, this is like Christmas came early…except instead of leaving decent stuff, Santa left….math. [Coop pointing at a blackboard]
- 01:05
…What, was he out of coal….? [Boy looks excited by presents under the tree then realises they're all math books]
- 01:08
So this circle’s got an angle measurement, too.
- 01:11
It’s called a “full angle”. [Cirlce with eyes]
- 01:12
It’s twice the size of a straight angle and
- 01:14
measures 360-degrees. [Dino pointing at a blackboard]
- 01:17
And what about the angles that are more than 180-degrees but less than 360-degrees?
- 01:21
Math’s not gonna let them fall through the cracks. [Angle falls down then comes back up]
- 01:24
We call those “reflex angles.”
- 01:26
And they're the real winners here, because they get the coolest name of the bunch.
- 01:30
So now you know.
- 01:31
Angles are everywhere, hiding in plain sight… [The light shines on the angles in the dark room]
- 01:34
…Seriously, can someone get these things a lamp?
