AI Thread Summary
The discussion explores whether there is a geometric interpretation for the multiplication or power of angles. Participants note that angles lack dimensions, making their multiplication akin to scaling rather than a geometric operation. The concept of solid angles is introduced, suggesting a potential relationship between plane angles and their products, though no definitive geometric interpretation is established. An analogy is made between multiplying lengths and finding an area, specifically referencing the surface area of a unit sphere defined by angles. The conversation concludes with a call for a more precise correlation rather than an approximation.

Exist an geometric interpretation for the multiplication of 2 angles? Or exist an geometric interpretation for the square/cube of an angle?

Your question is rather vague.Please Explain it more.
 
As in: ##\theta_1+\theta_2## would mean that an object underwent two rotations ... so what would ##\theta_1\times\theta_2## mean?

Angles don't have any dimensions - so multiplying angles is the same as scaling them.

If I had asked what geometrically means the sum of 2 angles, you, probably, show me a draw like:

But if I ask what means α×β, what draw you show me for illustrate such product?

But exist the solid angles...
 
I have never come across a situation where angles are multiplied together. To the best of my knowledge there is no reason to do this, so there is no geometric interpretation.
 
I was thinking if the solid angle could have some relationship with the product between plane angles...

We-ell, by analogy to multiplying two lengths you could argue for an angle-equivalent to an area but I don't know what that would mean.

The area of the surface of a unit sphere inside angles ##\theta## and ##\phi## would be (approximately) ##\theta\times\phi## ... that the sort of thing you are thinking of?

(Here the angles have to be specially defined.)

Yeah! But, I was looking for a exact correlation not approximate...
 
Well you could work out the exact version if you like - that's just algebra.
How do you find the area of a bit of a sphere?
