In an equilateral triangle, the sides will always be equal.

In an isosceles therefore of 120 degrees, the sides of the 120 degrees will also be equal.

Does hexagon having equal length sides also has equal angles?

Answer (1 of 3): > Does hexagon having equal length sides also has equal angles? No. “Equilateral if and only if equiangular” is only true for triangles; it is not true for quadrilaterals (a rhombus is not [necessarily] a square), etc. As a simple counterexample, consider two hexagons with side...

Many of people thinked like you but it actually work

Suppose each side is actually 40, then 40 - 29 = 11, 40 - 28 = 12 and 40 - 27 = 13.

From this I gather opposite sides of a rectangle must be equal.

The problem clearly says each side of the hexagon has the same length

Since it is a hexagon, the two sides towards the inside angle must be an isosceles?

Yes

I meant the inner line, the ones crossing each other in the middle.

You meant the diagonal lines, the diagonals length's aren't the same

What are your qualifications? What do you study?

"an object motion will remain in motion unless acted on by a force..." Newton.

Yeah... That's why light just keeps on travelling because it has no mass.

So as light doesn't have a physical form, force cannot be applied to it to stop it so it remains moving for eternity. But why is the light at motion ? And not rest?

@ Mods don't mind me posting in this thread after so long as I'm updating this thread since I came back from a long break from 2025.

It's good to have scientific discussions as it can attract high IQ people into this forum who in turn will also give constructive advice for looksmaxxing.

Just doing my bid to improve the forum's quality instead of the shitposting.

I was actually working on this. I think it has to do with Permeability and Permittivity of free space.

Does space have dimensions? Does light only travel in specific number of dimensions?

If I had a time travel/teleportation machine. Can I enter it with a light bulb on and go from space location and time A to space location and time B with the light still shining?

Didn't understand the teleportation question? I mean if the source of electricity of the bulb is also traveling with you (imagine the time Machine as a commercial lift) then it should shine at location and time B no?

It's not as easy buddy. It's not just objects travelling through other dimensions and re-entering into the observable universe in order to travel through time/teleport. That's why I stated Permittivity and Permeability of free space. Meaning light can only through 3 dimensions/space.
