Why does gravity makes planets round shaped?
A sphere is the minimum average surface area for a solid volume. Natural processes tend towards the lowest energy state (entropy).
If one considers the gravitational force to be a point source, then an effective gravitational "center of mass" can be established by a collection of points.
Agglomerating particles will therefore form spherical clumps as opposed to triangles or rectangles in an effort to reduce the energy potential between the bodies.

Because there is equal force applied in all directions, matter is drawn towards the center by gravity, forming a spherical shape.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
