Problem 50 What is the measure of an exterior angle of a regular hexagon?

And they have some wonderful properties.

So I have one, two, three, four triangles.

Therefore, you need to name it.

Maybe make it into a square.

An hexagon has six sides.

A hexagon has six sides.

If you wanted to get 16 lightbulbs' worth, then we're talking about these eight hexagons down at the bottom right.

So let's say that this is my virus.

That's symmetric, and it collapses down into these three triangles, which collapse down into one triangle, and collapsible hexagons are, you suppose, cool enough to at least amuse you a little bit during your class.

With four, you make a square, you make a pentagon, you make a hexagon, you make all these kind of polygons.

In fact, there's enough space here to keep wrapping the strip, and then your hexagon is pretty stable.

Using triangulation or tessolation, what is the minimum number of triangles you can use to represent this hexagon?

And then we have something interesting

Geometric Four Point Star

Geometric Five Point Star

Geometric Heptagon

Geometric Pentagon

Geometric Six Point Star

Geometric Seven Point Star

Block Arrow Pentagon

Geometric Octagon

Flatland is populated by geometric shapes, ranging from isosceles trianges to equilateral triangles to squares, pentagons, hexagons, all the way up to circles.

I've gone and had an fMRI myself, to see how my visual cortex is taking over.

Let me draw it a little bit neater than that.

So it's 1 2 ab.

Uh, it's a triangle.

We're on problem 15.

Triangle ABC equals Triangle Aprime, Bprime, Cprime.
