Is there a word for a collection of shapes?
For example: one triangle, two squares and three circles.

5What is the common characteristic of these shapes? What ties them together as a group? For example, I could have suggested polygon, except that you mentioned the circle, which has no sides or angles. If you want the word for "all possible shapes", with no further qualification, then the word is simply shape.– Dan BronJun 25, 2015 at 21:05

1Closed plane figures if they are closed like a triangle or square; just plane figures if they aren't all closed.– John LawlerJun 25, 2015 at 21:26

I don't think he's looking for a word for the concept of shapes. He wants a word for a collection of specific shapes. But I'm not aware of such a word. Can you show the context where you would use the word?– BarmarJun 26, 2015 at 10:35

@DanBron: But isn't a circle a polygon with infinite sides? Your suggestion holds good, I'd say.– Tushar RajJun 26, 2015 at 10:46

@TusharRaj You have to be very careful with limits. Saying "X is Y in the limit" is very different from saying "X is Y" without the qualification. If you conflate the two you quickly start running into mathematical absurdities and contradictions. It's a very common sort of category error kids will make when they first start learning algebra and later calculus, and leads to no end of amusing stories and situations. But, if you still like polygon, Josh Thomas has offered it in his answer, so you could upvote him.– Dan BronJun 26, 2015 at 10:58

That would be geometric shapes.
two-dimensional geometric shapes are called polygons and include triangles, squares, and pentagons. Others may be bounded by curves such as the circle or the ellipse.

If you're going to quote, don't introduce errors. 'Many two-dimensional geometric shapes can be defined by a set of points or vertices and [straight] lines connecting the points in a closed chain, as well as the resulting interior points. Such shapes are called polygons and include triangles, squares, and pentagons' Jun 25, 2015 at 21:26
"Geometric shapes" is a good answer. But perhaps not exactly what you're looking for.
Your examples are all basic shapes, like "circle, triangle, and square." These are all two-dimensional figures. Since "geometric shapes" can be of any dimension, the best answer for you may be: "two-dimensional geometric shapes."
Informally, you could just say "two-dimensional shapes" or even "two-dimensional figures."
If there are no circles in the group, and if you don't want to use the word "shapes" (which by definition is a group of shapes), perhaps you could use polygons.

A "polygon" has straight sides. Yes, you can approximate a circle with an infinitely-sided polygon, but it's probably not what the OP wants. Aug 25, 2015 at 2:21

Probably the term you are looking for is geometrics:
Straight lines and simple geometric shapes, e.g., circles and squares, used together to form a design or pattern. (ODO)
A pattern or design characterized by the use of geometric figures: Bright geometrics enhance the cloth's appearance. (AHD)
Polyform: a plane figure constructed by joining together identical basic polygon
Eg: Polyomino: a plane geometric figure formed by joining one or more equal squares edge to edge
Eg: Domino: a polyomino of order 2
Briefly, polyform is the enumeration of all possible shapes. The game Tetris was designed with a set of tetrominos forming a rectangle.
Here's a picture of a circle formed by polyominoes:
Is padstack the term you're looking for?
Padstack
A "padstack" is a collection of geometric shapes appearing on each of mask layers surrounding a through-hole in a printed circuit board. There are also padstack-related geometries associated with surface-mounted devices. The "Padstack Library" is one of the libraries present in the central library. Each padstack in this library is a representation of a pad or through-hole to be used in a design. Padstacks are referenced in making Cells; they are very detailed. They contain exact dimensions that must precisely correspond to the description of the manufacturer's package. Our central library has most of the padstacks that we will need already defined, so once you import all of the padstacks to your project's central library, there should be no need to edit them or to create more. If you have the need to create more, access the padstack tutorial for further information.
