Detorque. Detorque.

So we could draw that here.

An angle of 90 degrees is called a right angle.

Some people would call this the reflexive property

We were given if that is 90 degrees then this angle over here is supplementary to it and it also has to be 90 degrees.

Do I do it upside down?

Now, we can use that exact same logic

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

And this measure of how fast you're orbiting around a central point is called angular velocity

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

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

Trigonometric functions use degree mode for angles.

But this is just general terminology for different types of angles

Angular velocity

Seed radius

Cut off angle

Angle Mode

Watermark Angle

So, for example, we wanna prove that CAB is congruent to BDC

Now the other thing that we know

Now what else can we figure out?

C A sorry CAE I should say is congruent to triangle CAE

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.

Main angle

Main horizontal angle

Main vertical angle

Arc angle

Rotation degree

Y angular velocity

Z angular velocity

Combine angle

Shadow Angle

Drawing angle

Four degrees elevation.

So for example, let us take two angles here, angle BAC, and let's say over here, I have angle XYZ when you look at these angle XYZ is more open while this angle is more closed, compared to the other angle when we measure angles, we must measure it on how open or closed they are.

So angle angle side orange sorry, orange angle white angle side
