Question 2- Determine the AP whose third term is 5 and seventh term is 9. Question 3- If any point is equidistant from the points (a+b, b-a) and (a-b, a+b), prove that bx = ay. Question 4- If the line segment joining the points A(2,1) and B (5,-8) is trisected at the points P and Q, find the coordinates of P. Question 5- If, from an external point P of a circle with centre O, two tangents PA and PB are drawn such that ∠BPA=120, then show that OP = 2PA. Question 6- Prove that the tangent drawn to a circle at the end points of a diameter are parallel to each other. Question 7- Find the value of p for which the numbers 2p-1, 3p+1, 11 are in A.P. Hence find the numbers. Question 8- Find the coordinates of the points of trisection of the line segment joining the points A (7,-2) and B (1,-5). Question 9- Find the coordinates of the point on x-axis, which is equidistant from the points (-2,5) and (2,-3). Question 10- A circle touches all the four sides of a quadrilateral ABCD.
