See this
planarity why lost
how steric repulsion works on planarity
one phenyl ring will be in plane & other will be orthogonal to the plane due to steric repulsion
what is orthogonal is this case
If steric repulsion is not there then molecule will be planar. Then it will optically inactive
perpendicular dear. I have drawn in the paper. Orthogonal means plane ke perpendicular. See I drawn with wedge dash notation

ok tq for explaining easily
