I have two geometry problems

[alibabakes5]

As the title says I need some help with two geomtry problems:

1: The cathets AB and AC of a right triangle are 1 cm and 8/9 cm. Determines at what distance from C on the AC side and from B on the AB side two points R and S must be taken such that the three segments CR, RS and SB are congruent.

2: Un triangolo equilatero ABC ha il lato di lunghezza 4 cm. Prendi su ognuno dei lati del triangolo ABC rispettivamente tre punti D, E, F alla stessa distanza p dai vertici e nello stesso senso, in modo che il triangolo DEF sia un triangolo equilatero di area uguale a 7/16 dell'area del triangolo ABC. Determina la distanza p.

Thanks for the help.

What if you where inside a hollow sphere. Light would get bended around the perimeter so if you were on the perimeter, would you be able to see your back. Like imagine I’m in a hollow spheres and I role a ball around it. The ball would loop around and assuming it would go perfectly straight, it would hit me. Now what if it was like this for light and instead of hitting your back, you see your back. Don’t know if this makes sense but can anyone explain how this might work or if it would even make sense? Also, what would this look like in a 3D first person perspective? Would there be a way ro program this into a game to see what it would look like?
