Q2 of 12 Page 242

Draw ⨀ (O, 4). Construct a pair of tangents from A where OA = 10 units.

Steps of Construction:


1. Draw a circle of radius 4cm and center O.


2. Draw a line OA such that OA= 10cm



3. Draw a perpendicular bisector of OA which cuts OA at M.



4. Taking M as center and radius OM, draw a circle.


5. The two circles intersect at P and Q.



6. Join AP and AQ. AP and AQ are the required tangents.
