You also have a rotation matrix that will rotate the model or anything else around the y axis.

They run in different directions.

It's called antiparallel, so they label the ends.

The r matrix rotates the model on its base.

And if you think about it, if both of these things are true, then actually not only is A inverse the inverse of A, but

The model's locations are now rotated.

First of all, a rhombus is a special case of a parallelogram

So that's a special case of a square di, diagonal matrix.

And let's see if we can simplify this a little bit.

I'mI'm heading in the wrong, wrong direction.

So how did I find this inverse or how did I come up with this inverse over here?

So that right there is the transversal.

Let's look at the inverses of some common transform matrices.

I'd like you to identify the types of matrices these are.

1 Staple, parallel

2 Staples, parallel

3 Staples, parallel

6 Staples, parallel

It looks just like x.

Level out! That's it.

The opposite sides of a parallelogram are parallel.

For example, if your matrix moves an object five units up, the inverse moves it five units down.

And minus 3 7.

It's so taxing on me.

Let's calculate B inverse.

Fire!

And then I thought, Why stop there?

So we're literally just factoring out a 2x plus 5, and we're left with an x plus 6.

That looks right.

Mutiny. Mutiny.

Parallel to this line?

So if I just wanted to draw vector v in standard position,

That point right there.

Well, now, that is simply not the case.

But one of my favorites that I love to solve these kind of chess puzzles, is called retrograde analysis.

Well, it means don't drink and drive.

So this is the adjoint of matrix a.

A parallelogram is a quadrilateral formed from two sets of parallel lines.

Translations can be added together to get a single translation vector.
