Let me do an ellipse in another color.

And in fact, what's even the relationship.

And if I tilted it the other way, the ellipse would squeeze the other way.

Now, another super interesting, and perhaps the most interesting property of an ellipse, is that if you take any point on the an ellipse, and measure the distance from that point to two special points which we, for the sake of this discussion, and not just for the sake of this discussion, for pretty much forever, we will call the focuses, or the foci, of this ellipse.

So this is still elliptical shapes.

So that's the origin right there.

So, just to make sure you understand what I'm saying.

It's really manifested there.

Makes an elliptical or circular selection

It'll be perfectly round.

Ellipse by Focuses Point

This is our x axis and this is our y axis.

And here is a blatant example of dust in a elliptical galaxies.

This magenta distance minus this light blue distance.

So you go up 2, then you go down 2.

Even in our immediate neighbor Andromeda

And the way I drew this, we have kind of a short and fat ellipse you can also have kind of a tall and skinny ellipse.

There's no way that you could this is the exact center point the ellipse.

Actually, you probably recognize a few of them already, and I'll write them out.

But this is a general sense.

In the last video, we learned a little bit about the circle.

If you keep kind of tilting if you start with a circle, tilt a little bit, you get an ellipse.

Construct an ellipse with this focus

Well, I didn't draw it that well.

It pops and it turns into a parabola.
