What is the geometric shape of the number 7?

Answer 1

I'm looking at a number seven and it looks like it has seven sides. See link #1. So it would be a seven-sided polygon or a heptagon (sometimes called a septagon).

(But it is not a regular heptagon because the angles and sides are not equal. And it isn't convex, because it has an interior angle that is greater than 180.)

Therefore the correct answer is that the number 7 forms a seven-sided (non-convex, non-regular) heptagon. You could get different answers depending on the font used for the seven and how it was drawn so this isn't the only answer, but I like the fact that the 7 I picked had seven sides. :)

Answer 2

7 is the second centered hexagonal number. A centered hexagonal number is a number that can be represented by a dot in the center and the rest of the dots arranged in concentric hexagons around it. The first 5 centered hexagonal numbers are 1, 7, 19, 37, 61.

7 is also a heptagonal number. The first 5 heptagonal numbers are 1, 7, 18, 34, 55

Answer 3

Ask somebody with synaesthesia in mathematics.

Research for a British man who can see and feel numbers, and can evaluate very complex mathematical problems and patterns without pen and paper, because he can see and feel the numbers and then see and feel the answer.

He recited pi to the 20,000th decimal without stopping for 12 hours I think.

Answer 4

I assume you mean the numeral 7, since the number doesn't really have a "shape."
Let's go with angle. It's not precise, but it'll do.

Answer 5

Since 6 is hexagonal (http://www.research.att.com/~njas/sequences/?q=hexagonal&sort=0&fmt=0&language=english),
7 is septagonal

Answer 6

number seven does not have gemetry. Its like an adjective to something else
