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

Degrees

Radius

X angle

Y angle

X angle

Y angle

Do I do it upside down?

Now, we can use that exact same logic

So we could draw that here.

An angle of 90 degrees is called a right angle.

And this comes straight from once again, orange angle white angle side

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

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

Now, we know that corresponding angles must be congruent

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

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

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

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.

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

and we know that by corresponding angles congruent of congruent triangles

Impossible angle.

Some people would call this the reflexive property
