Hexagon

A hexagon

Six sided cells

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

Geometric Hexagon

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

And they have some wonderful properties.

Maybe make it into a square.

An hexagon has six sides.

A hexagon has six sides.

Therefore, you need to name it.

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.

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?

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

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

The sum of the interior angles of this hexagon, of any hexagon, whether it's regular or not, are going to be 4 times 180 and that's 720 degrees.

Let's just do it.

So once again, I like to just draw a hexagon.

Fit falling blocks together on a hexagonal grid

Let's go get the dough. Listen, we're not in the clear yet.

Studying pollen grains and radiolaria and carbon molecules helped us devise the most efficient structural solution using hexagons and pentagons.

Let me draw it a little bit neater than that.

And then we have something interesting

And it deals with right triangles.

So it's D.

A very fancy word for a very simple idea.

Intersect this polygon with another polygon

And since that is a triangle that has a 90 degree angle, it's a right triangle.

How do I know it's not 15 or 16?

So it's 1 2 ab.

Uh, it's a triangle.

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