Question

Number of tangents on a circle

The number of tangents drawn from a point on the circle depends on the position of the point with

respect to the circle. Suppose O is the centre of a circle of radius 5cm. T is a point such that OT=13cm

and OT intersects the circle at E and AB is the tangent to the circle at E



a) Find the length of the tangent at point T

i) 12cm ii)13cm iii)14cm iv)15cm

b) Find the length of tangent AB

i) 20/7cm ii)20/3 cm iii)10/3 cm iv) none of these

c) How many tangents can be drawn from point O

i)0 ii)1 iii)2 iv)3

d) Find the area of triangle ABT?

i) 80/7 cm2

ii) 80/3 cm2

iii) 80/11 cm2

iv) none of these

e) If two tangents are drawn to a circle at the ends of a diameter then the tangents are:

i) equal ii) perpendicular iii) parallel iv) none of these​
