More hexagons!

Earlier in the week we all used Geogebra to create a lot of different hexagons. Here are a few of them:

We discussed how to describe their features. 

Some of the features we mentioned are:

• pairs of edges which are parallel
• edges which are the same length

and at the corners:

• right angles
• acute ("sharp") angles
• obtuse ("blunt") angles

• symmetry

Then we made some more hexagons out of geostrips:

Here they are:

But wait...

This one isn't a hexagon!

And is this a hexagon??!

 This one was interesting. We needed to pull at six corners:
