One of the areas in vector proofs i think in vce revolves around geometric shapes, rectangles, squares and all that shizz, one really important thing is to know what are the mathematical definitions of a square, rhombus etc then prove the mathematical definition. So remember, a rhombus is just a parallelogram where all four sides are equal. Since the tangent line to a circle at a point P is perpendicular to the radius to that point, theorems involving tangent lines often involve radial lines and orthogonal circles.
