If the segment joining the points (a, b) and (c, d) subtends a right angle at the origin, then. The coordinates of P(, Then the distance between the two points P and Q will be given by the. Download free CBSE Sample paper for Class 10, Math. Then the distance between the two points P and Q will be given by the Distance Formula, PQ =√ [(x2-x1 )2 + (y2-y1)2] OR (PQ)2 = (x2-x1 )2 + (y2-y1)2. In triangle ABC, D and E are mid-points of the sides BC and AC respectively.

Observe the solutions and try them in your own method. Q5) Find the area of the triangle with vertices (5,4) , (7,1) and (4,2). ... 3. Hence we can check whether three points are collinear or not bye finding the area of the triangle and if it comes to be 0 then they are collinear otherwise not. If any point P(x,y) divides the line segment AB in the ratio m:n then the coordinates of P(x,y) cab be find using the section formula: x = (mx2+ nx1 ) / (m+n) and y = (my2+ ny1 ) / (m+n), x = (mx2- nx1 ) / (m-n) and y = (my2-ny1 ) / (m-n), Here an important point is to be remembered that if P is the mid-point of the line segment AB, then the value of both m and n will be that is the ratio will be 1:1. The first coordinate or x-coordinate in this case is 4 and the second coordinate or y-coordinate is 3. y-coordinate, or ordinate. Observe the example problems and solutions. x-coordinate, or abscissa. Note : Observe the solutions and try them in your own method. EX 7.4 Class 10 Maths. Therefore, on using the distance formula we get, (2-x)2 + (-5-0)2 = (-2-x)2+ (9-0)2 (On squaring both the sides). PQ =√ [(x2-x1 )2 + (y2-y1)2] OR (PQ)2 = (x2-x1 )2 + (y2-y1)2 SSC solutions for maths Coordinate Geometry Mathematics solutions for Coordinate Geometry class 10 SSC.
