82　About the number  "7" and its around 
④　" 7"　and the Pyramid
～60 Stars Astrology ( Off Season 8)

1. Since we are talking about around the number "7", I will write here about the number 7 as represented in the pyramid.

I am talking about why a pyramid is sloped at a little more than 51 degrees.

Well, this is just Tanu‐chan's fantasy!

2. Before that, let's speculate on the ideas of the people who built the pyramids.

I think that they were all very interested in making a three-dimensional object out of a two-dimensional figure on the ground.

For example, when we think of making a circle into a three-dimensional object, modern people immediately think of

4/3π×r cubed

but that's talking about volume.

In terms of surface area, a sphere is,

4 x π x r squared

In other words, 4 circles with an area of π x r squared, arranged horizontally at right angles, form a three-dimensional (sphere).

In the same way, if we consider the case of a square, 4 squares arranged horizontally at right angles make a box (cube).

3. Then, let's put 4 triangles side by side at right angles.

If you do this, the top surface will be a little bumpy.
So, we can make a pyramid by slanting the triangles.
(Fig. 1)

4. Now, let's consider what kind of triangle they had in mind.

Is it an equilateral triangle?

I don't know.... it is a bit difficult question for me.

So, well, for now, let's assume that its width is L and its height is H.

(Fig. 2)

５. Then, if we slant it to form a pyramid, the vertices will overlap at a certain point, and we will stop there.

Then the pyramid will look like the figure below when viewed from the side.
(Fig. 3)

6. Now, let a be 90 degrees divided by 7 as "a".

Then, the angle when viewed from the side of a pyramid(one of the three great pyramids) is shown in the figure below.
It is a beautiful figure!

(Fig. 4)

7. Then the angle of inclination is 4a, so 90°/7 x 4 = 51.4°.

You can also see the number 22 in the figure!

So, 7 and 22 are good friends!

And π is also approximated by 22/7, right?

Well, this is how the number 7 is used in the pyramid.

…But, it would be better to consider what kind of number is used for each of the three great pyramids. 

Because the angles of inclination of the three are also a bit different !

8. By the way, if we assume 90°/7 = a, the interior angle of a heptagon is 10a, and the sum of all the interior angles is 70a in total.

So, 7 and 10 are also good friends!

...If you look at the pyramid in a different way, you might possibly find a different figure, different numbers....
