Types of Quadrilaterals and Other Polygons

Shapes! They're so fun. But they're even more fun when you know precisely how to define them. What's a rhombus? What's a parallelogram? Did you know that squares are rectangles? And both squares and rectangles are parallelograms? There's a whole hierarchy! Seriously, get into this stuff.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

I’m doing this in 2021 and this is very helpful for me because I’m literally learning the same thing with shapes so thanks

Kinds of Polygon

3- Triangle
4- Quadrilateral
5- Pentagon
6- Hexagon
7- Heptagon
8- Octagon
9- Nonagon
10- Decagon
11- Undecagon
12- Dodecagon

(Thats all i know cause im only grade 5 😂)

A chevron or arrowhead shape has 4 sides, so it too would be a quadrilateral.

Hi Dave. Will you be doing a series on formal logic?

[cameroncarsdocspitcrew.]

I HAVE A QUESTION: EVEN THOUGH IA, M A NEWBIE TO THIS CHANNEL, YOU SEEM PRETTY SMART!. So I Have A Question: WHAT IS A QUADRILLION SIDED SHAPE CALLED?. AND DOES A QUADRILLION HAVE 155 SIDES?.

[karljhoy]

Hi Dave. Thank you for making this video

[ahmedemad]

Professor dave how about edge and vertices and pyramid, prism

[Chezika]

Im watching this because i have a test tom and i forgot my reviewer at school so im f0cked
