Drawing angle

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

Yes, I understand the timing now.

Well that seems like that would be the last step. Then you're done.

Change your screen resolution

non labeled to pink to green CBD and this comes out of angle side angle congruency

Right, what I have right in front of me is the Khan Academy measuring angles, measuring angles exercise.

Well, everybody can throw around big numbers.

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

And now we have something interesting going on, we have an angle, a side, and an angle

This is an altitude of it, it splits it into two symmetric right triangles, it bisects the opposite side, it's essentially a median of that triangle.

And the entry point for his right hand notice this, he's not reaching in front and catching the water.

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

Allow tight turns

Now, we can use that exact same logic

And for talking about relatively short periods of time,

An angle of 90 degrees is called a right angle.

Now the other thing that we know

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

Now, we know that corresponding angles must be congruent

Now what else can we figure out?

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

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

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

Arc angle

Shadow Angle

And you can see that it's pointing to right about well let's just say to right about the 30 degree mark.

Degrees

Y angle

Do I do it upside down?

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

and we know that by corresponding angles congruent of congruent triangles

So the first thing that pops out to me is that we have one triangle right over here, we have this triangle on the left, and on this triangle on the left we are given two of the angles.

Obviously, this is a right angle

This box displays an angle in degrees. The three numbers displayed are the angle's degrees, arcminutes, and arcseconds.

So we could draw that here.

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

A second purpose is 3D reconstruction.
