Distance of geodecis on the surface and angles between them (objects on a surface)

Needs Answer

I was trying to find the angle EBD along the surface of the sphere also the distance BD (along the shpere), to generalize if I need to verify Riemannian distance (ie) verifying Pythagoras theorem along any surface to find it's curvature,

Is there a general way to do this in geogebra I tried to find documentation but even for the simple case of sphere I'm struggling

any help is much appreciated.
