Draw a pair of tangents to a circle which are inclined to each other at an angle of 80∘.
The tangents can be constructed in the following manner: Step 1: Draw a circle of radius 5 cm and with centre as O Step 2: Take a point A on the circumference of the circle and join OA. Draw a perpendicular to OA at point A. Step 3: Draw a radius OB, making an angle of (180∘−80∘) with OA Step 4: Draw a perpendicular to OB at point B. Let both the perpendiculars intersect at point P. PA and PB are the required tangents at an angle of 80∘
