Direct link to Epic Potato's post “A shape with four equal s...” A shape with four equal sides is called a square. A square is a rhombus because a rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. A square however is a rhombus since all four of its sides are of the same length.

Lateral in this sense means a shape that has straight sides that are part of the same geometric object. The "quad" in quadrilateral means it's a shape that has four of them. Hope this helps!

2 bi - think about bicycles
3 tri - tricycles
4 tetra - if you play tetris, you'll know it!
5 penta - sorry, I don't really have one for this...
6 hexa - just remember that if it starts with a 'h', it's either 6 or 7. And since 'hexa' contains the letter 'x', you know it is six. Seven is simply the other one :)
7 hepta - refer to above
8 octo - octopus
9 nona - sounds like nine, doesn't it?
10 deca - decade.tri- with the word tricycle, as it is a bicycle, but with 3 wheels. A triangle has 3 sides and angles. See more below:Octi- as in octopus. An octopus has 8 arms, and an octagon has 8 sides and angles.Quad- as in quad-bike. A quad-bike has 4 wheels, and a quadrilateral has 4 sides and angles.Hex I'd just memorize. :)
Need any more help? Just say so! :)
- hecto = 100
- gon = side

I was wondering if a triangle and hexagon are 3D shapes?
Similarly in quadrilateral, the quad is supposed to mean 4, but what is lateral supposed to mean here?
And what about circle? Why is the shape called a circle?
It is very cool that you are so puzzled about the nefarious circle! Humanity spent many, MANY years trying to understand a circle. A circle is an object with infinite sides, called a curve.
