When I was looking at a tetrahedral molecular structure, a question arose. In that molecule, there are 4 atoms placed around a sphere, where the bond angle between any two is 109.5(adsbygoogle = window.adsbygoogle || []).push({}); ^{o}. How could I show that? It's not part of the homework, but I'm just wondering how to find the angle if you have 4 equidistant points on a sphere. Spherical trigonometry maybe?

Thank you
