The only way to specify which can we are talking about is to give 3 letters if you want to talk about this angle, you will call it angle EHG, or could call it angle GHE, if you wanted this angle over here, you could call it angle DHG, or angle GHD. i think you get the point. this angle is angle FHE or EHF and this is angle FHD or

You have to have points B and C before you can draw those equal arcs.

Now, we can use that exact same logic

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

Angle BDC over here, it is an alternate interior angle with this angle right over here with that angle right over there

Now the other thing that we know

Now what else can we figure out?

Arc angle

Shadow Angle

Degrees

Radius

Angle

Angle

X angle

Y angle

Angle

X angle

Y angle

Do I do it upside down?

So, let me write this down

Obviously, this is a right angle

So we could draw that here.

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

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

Angle value in degrees.

Angular velocity

Seed radius

Cut off angle

Angle Mode

Watermark Angle

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

I'm talking about triangle ABF and triangle ACE and they both share this vertex at A and point A is a vertex for both of these

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!

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

Now we want to use the same sides white angle yellow side then orange angle

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.

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

Now, both of these triangles are also isosceles triangles, so their base angles are going to be the same. So that's one base angle, that's the other base angle.
