It leaves a bruise.

That means side, side, side.

So all them by side side side they are all

So, this is by side side side

And this is by Side Side Side (SSS) congruency.

Because they are congruent by Side Side Side (SSS).

We don't rigorously prove side side side

A side a side and a side

We don't rigorously the prove side side side theorem

ECG by side angle side congruency, by side angel side congruency

So, we know that by side side side that they are congruent

But I wanna be clear sometimes you'll hear this referred to as a side side side theorem theorem and sometimes you'll hear it as a side side side postulate or axiom postulate or axiom.

I gave him a black eye for it and had to tie him up to a tree.

And whether you can spout out, side, angle, side, and angle, side, angle.

If you go back to your 9th grade Geometry unit, you'd use the Side Side Side (SSS) theorem if three sides are congruent, then the triangles themselves are congruent.

So you see by side angle side

Side angle side, these 2 triangles are going to be congruent

Plus, the two triangles are congruent because of the side side side congruence theorem for triangles.

By the side, side, side reasoning, these are both congruent triangles.

And so by side side side, so by side side side we know, we know that triangle, triangle ABC triangle ABC is congruent to triangle AE

We know that triangle ADC is going to be congruent to triangle ABC and we know that by side side side congruency

We know, it should let me write it over here by side side side we know, we know that triangle AEC, AEC is congruent to triangle AED.

You don't want someone else to get paid more just because they were willing to say SAS, ASA.

It's a side on both of them.

We have a side in between that's congruent

I multiply the base by itself.

So we've done one of the sides

A side that is congruent to this side over here.

Fine. But don't complain if you get bruised or break anything.

And then so, we could say by the side, side, side reasoning, I'm not that good with terminology.

So, we know that triangle, I'm gonna start at A and I'm going to the one half side, so, ACB is congruent to triangle DBC and this is by side side side congruency

So I'm going to take the second derivative, y prime prime, so that's minus A sine of x minus B cosine of x.

The base right here has length a.

It's a corresponding side on both of these triangles.

So, S is equal to 102 sides

Let's say they share the same base.

And how long are each of the sides going to be?

Both triangles have a side of length BD.

I'd like to break every bone in your body.

And then we see that triangle AEC must be congruent to triangle DEB by side angle side

It looks like every other incremental side

We have a side in between that's going to be congruent

Then we divide each side again just like that.

A side between the orange and the magenta

So given that, what is the length of each of the sides? Well, all the sides are going to have the same length.
