What is the acute angle where 4 lines meet at 1 point, and all 4 angles are equal?, ( if it was 3 lines, then 90˚ )?

Question

I am trying to build a 3D hypercube model, and I need to know the degrees of 4 line intersecting at 1 point, where all angles are equal, I think it somewhere between 72˚ and 80˚

Answer 1

When all four lines meet at one point, the eight angles form a circle.

360/8 = 45º

 

Three lines would form six angles. 360/6 = 60º
