Question
Write the step of construct the tangents to a circle from an external point.

Answer


Steps of construction:
  1. Take given circle and a point P outside the circle. O is centre of the circle.
  2. Joint OP.
  3. Bisect OP and get its mid-point M.
  4. Draw circle with centre M and radius = PM = MO.
  5. Circle drawn meets the given circle at Q above PO and at Q’ below PO.
  6. Join PQ and PQ’.
  7. PQ and PQ’ are the required tangents drawn to the circle from the point P.
We observe that PQ = PQ’.
