Electric field line originate from positive charge particle, and this is assumption or convention in physics to understand property of charges.
And whenever we assume any charge we always assume spherical one , we can also select any arbitrary shape like cylindrical or cubical . Whenever the electric field lines originate it will always be perpendicular from the originating point if it will originate at any different angle it will intersect other linear and at the point of intersection there will be two different field at that point and this is not possible .it will contradict our assumption that's why.
