Question

draw a circle of radius 4 cm and construct a pair of tangent to the circle from a point 5 cm away from the circle​

Answer 1

Steps for construction :

(i) Draw a circle of radius 4 cm

(ii) Draw a point A, 5 cm away from centre O

(iii) Join AO and make perpendicular bisector of AO

(iv) Let M be the mid point of AO

(v) Make a circle centred at M with radius MO

(vi) Let it intersect the given circle at B and C

(vii) Join AB and AC

(viii) AB and AC are the required tangent
