Construct a circle of radius 3 cm and mark a point P on it. Construct the tangent to the circle at P and justify the construction.
Original Khojo Papers practice question — not from a past board paper.
Answer
Join the centre O to P and construct the line through P perpendicular to OP; that line is the tangent.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
A tangent is perpendicular to the radius at the point of contact, so a line through P perpendicular to OP touches the circle only at P.
