And on top of that, what makes is even more extreme, is the actual angle that the... and of course this is to some degree due the fact of where the angle of the Sun in relative to the horizon or where you are on Earth, but even more than that, if you are on...

I believe acute, in either latin or greek or maybe both means something like pin or sharp, so that's one way to think about it an acute angle seems much sharper.

Even if your paper doesn't have an edge, you can just fold it and ta da Angle A Tron!

And I'll talk about more types of angles in the next video, but if an angle is less than 90 degrees so for example both of these angles that we started our discussion with are less than 90 degrees we call them acute angles.

And if you look at it that way you'll immediately see that angle

This is a right angle and then, this is a right angle

This length is equal to this length.

Now, we can use that exact same logic

This angle plus this angle is going to be equal to this angle.

Well this here is 58 degrees

Let's say it a little generally.

179.99, 179.98 and so on, each angle has probability zero.

Now the other thing that we know

Now what else can we figure out?

in a moment's time

Arc angle

Shadow Angle

We know that this angle right here, I'll draw it small, is congruent to this angle over here.

That means that that this angle here must be equal to 90 degrees minus alpha, which means this angle, since this is a right triangle must be alpha.

Do I do it upside down?

Towards the rising sun?

Obviously, this is a right angle

Towards the setting sun.

The front roller thrust angle is 2 degrees, probably there were plans to strengthen that angle a little when racing.

So we could draw that here.

It can write at any angle, in any temperature, in zero gravity

And that's the best angle of the courtyard?

An angle of 90 degrees is called a right angle.

Some people would call this the reflexive property

OK, so first of all, we have to remember what is the sum of the interior angles of a pentagon?

And they want to know, what is a measure in degrees of the

So, for example, we know that angle CDE is going to be congruent to angle BAE

Well, you might realize that we've just shown that both of these triangles, they have this pink angle and they have this side in common and then they have the green angle

Trigonometric functions use degree mode for angles.

But this is just general terminology for different types of angles
