Answer 1

Steps of Construction:
​Step 1: Construct a circle of radius 3.5 cm with centre O.
Step 2: Take a point P in the exterior of the circle such that OP = 5.7 cm
Step 3: Draw segment OP. Draw perpendicular bisector of segment OP to get its midpoint M.
Step 4: Draw a circle with radius OM and centre M.
Step 5: Name the point of intersection of the two circles as A and B.
Step 6: Draw line PA and line PB.

Here, line PA and line PB are tangents to the circle from point P.
