NUMBER SYSTEMS - NCERT
By Pythagoras theorem, OB = 13 Using a compass with centre O and radius OB, draw an arc which intersects the number line at the point C. Then, C corresponds to 13. Remark: We can also take OA = 2 units and AB = 3 units. Sample Question 2 : Express 0.123 in the form p q, where p and q are integers and q ≠ 0. Solution : Let x = 0.123 so, 10x = 1.23

ncert.nic.inThe theorem can also be proved by using the Pythagoras Theorem as follows: PQ2 = OP2 – OQ2 = OP2 – OR2 = PR2 (As OQ = OR) which gives PQ = PR. 2. Note also that ∠ OPQ = ∠ OPR. Therefore, OP is the angle bisector of ∠ QPR, i.e., the centre lies on the bisector of the angle between the two tangents.
