Mid-point of AB is (2, – 3), which is the centre of the circle. 2. Determine if the points (1, 5), (2, 3) and (-2, -11) are collinear. What is the ordinate of any point on x-axis? Let P (x1, y1) and Q (x2, y2) are the points of trisection of the line segment joining the given points i.e., AP = PQ = QB. Download NCERT Solutions For Class 10 Maths Chapter 7 Coordinate Geometry PDF. Therefore, the coordinates of the point of division, say P(x, y) is ((-4k+1)/(k+1), (5k-5)/(k+1)). Draw a figure, line dividing by 4 points. If A and B are (-2, -2) and (2, -4), respectively, find the coordinates of P such that AP = 3/7 AB and P lies on the line segment AB. Therefore, point P divides AB internally in the ratio 1:2. y1 = (1×(-3)+2×(-1))/(1+2) = (-3-2)/3 = -5/3. NCERT Solutions for Class 10 Maths Chapter 7 Exercise 7.2 in English & Hindi medium or View in Video Format updated for academic year 2020-21. Let say this point be P(x, y). Chapter 1 - Real Numbers. After joining these points a triangle is obtained by her. What values are depicted in the question? From the figure, it can be observed that points X, Y, Z are dividing the line segment in a ratio 1:3, 1:1, 3:1 respectively. Exercise 7.1– 10 Questions (8 practical based questions, 2 reasoning questions), Exercise 7.2- 10 Questions (8 long answer questions, 2 short answer questions), Exercise 7.3– 5 Questions (3 long answer questions, 2 practical based questions), Exercise 7.4– 8 Questions (6 long answer questions, 1 practical based question, 1 reasoning question). Niharika runs 1/4 th the distance AD on the 2nd line and posts a green flag. If Rashmi has to post a blue flag exactly halfway between the line segment joining the two flags, where should she post her flag? Find the coordinates of the points of trisection of the line segment joining (4, -1) and (-2, -3). 6. Similarly, Preet posted red flag at 1/5 of the distance AD i.e., (1/5 ×100) m = 20m from the starting point of 8th line. Find the coordinates of a point A, where AB is the diameter of circle whose centre is (2, – 3) and B is (1,4). To solve a riddle a girl is asked to join the three points A(7, 5), B(2, 3) and C(6, –7) with a sketch pen. CBSE recommends NCERT books and most of the questions in CBSE exam are asked from NCERT text books. NCERT Solutions for Class 10 Maths. All questions have been solved in an easy to understand way with detailed explanation of each and every step.Answers to optional exercise is also givenIn Coordinate Geometry of Class 9, we learned w If a point A(0,2) is equidistant from the points B(3,p) and C(p,5) then find value of p and the length of AB. Since the diagonals of a parallelogram bisect each other, the midpoint is same. Therefore, the coordinates of this point are (2, 25). 6. 3. Find the ratio in which the line segment joining A (1, – 5) and B (- 4, 5) is divided by the x-axis. NCERT Solutions for Class 10 Maths Exercise 7.2 Class 10 Maths book solutions are available in PDF format for free download. We know that y-coordinate of any point on x-axis is 0. So, x-axis divides the line segment in the ratio 1:1. Tutorial for Learning C Programming: Is It Possible to Learn the Programming Language Online?

NCERT Solutions and Offline Apps are available for Gujrat Board (GSEB), CBSE Board, MP Board, UP Board, Uttarakhand, Bihar Board and other boards who are following NCERT Books 2020-21 for their course based on Latest CBSE Curriculum 2020-21. A teacher asked three students to stand to form a triangle at the points P (–1, 3), Q (1,–1) and R (5, 1). 1. The coordinates of point A and B are (-2,-2) and (2,-4) respectively. Suddenly a fourth boy came and shows his interest in participating the activity. Therefore, Rashmi should post her blue flag at 45/2 = 22.5m on 5th line. x = (2+8)/2 = 10/2 = 5 and y = (20+25)/2 = 45/2. 2. Distance between these flags can be calculated by using distance formula. 2. [Hint: Area of a rhombus = 1/2(product of its diagonals). इस प्रश्नावली के प्रश्नों में विभाजन सूत्र द्वारा किसी रेखाखंड का मध्य बिंदु, उसको किसी विशेष अनुपात में विभाजित करता हुआ कोई बिंदु तथा त्रिभुज के केन्द्रक पर आधारित प्रश्न हैं।.
