Why can a tangent not be constructed from a point inside a circle?

Original Khojo Papers practice question — not from a past board paper.
Each side is 5 cm.

Stepping the radius round the circle with compasses divides the circle into six equal arcs, because the chord of a 60° arc equals the radius.
