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

Or this angle plus this angle plus this angle is equal to 180.

And we see that this angle and this angle, this angle has a measure of 4x, this angle has a measure of 2x.

The second angle, like in this clip.

Select this angle

This pink angle is supplementary to this 110 degree angle.

So this come straight angle angle side congruency

So, this is from angle side angle congruency

And this comes straight out of angle side angle

This angle down here is a vertical angle, that's gonna be a right angle

Attach to this angle

Rotate by this angle

So given this angle.

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

Arc angle is smaller than falloff angle in rainbow.

This function transforms a radian angle to a degree angle.

This function transforms a degree angle to a radian angle.

Now if this angle over here is a right angle

And at first you might say, wait, is this angle and that angle vertical angle?

This value in degrees will be added to main angle value to set fine target angle.

So this angle is theta, we have theta is adjacent to this angle

Angle is in degrees.

Angle value in degrees.

Angle value in hours.

Pink angle, side in common and then the green angle

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

Construct Bisector of This Angle

Projectively rotate by this angle

This is a right angle

One fr om this angle?

This is a right angle this over here is gonna be a vertical angle

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

And so if this angle right over here, if this angle right over here is 4x, it has a corresponding angle.

And so, if this angle is congruent to that angle, that angle is congruent to that angle, then they're congruent to each other

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

And we also we make this angle is equal to that angle.

That is a right angle and then this is a right angle

So, we're just saying that this angle is equal to that angle

So this pink angle theta plus this green angle must be equal to 90 degrees

So, angle DEC must be let me write this down angle DEC must be congruent to angle BAE

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

It's equal to angle ACE so this angle right over here is congruent to that angle right over there

This table is at an angle.
