Question

Radius of a circle is 5.2 cm and point p is at a distance 4.8 cm from the center of a circle the decide the place pointe p.

Answer 1

∆ Solution

Given: The radius of the circle=3.2cm.

Construction:

(i) With O as the centre, draw a circle of radius 3.2cm.

(ii) Take a point P on the circle.

(iii) Through P, draw any chord PQ.

(iv) Mark a point R distinct from P and Q on the circle so that P, Q and R are in counter clockwise direction.

(v) Join PR and QR.

(vi) At P, construct ∠QPT=∠PRQ.

(vii) Produce TP to T' to get the required tangent line T'PT.
