Suppose x y and z are the three points with which we can form three sets of pairs such that xy yz and xz are three pairs of points.
Points p q and r are collinear. Basics of coordinate geometry for more information on basics of coordinate geometry watch the below video. If you like this video then please share it with you.
With three points a b and c three pairs of points can be formed they are. Collinearity of three points use distance formula a b c show that ab c 21. If slope of ab slope of bc slope of ac then a b and c are collinear points.
Draw aq and pc parallel to the x axis. Draw ar ps and bt x axis. Go through the below article and learn the points on the coordinate plane distance formulas section formulas and so on with the detailed explanation.
Three or more points are collinear if slope of any two pairs of points is same. Three or more points are said to be collinear if the slope of any two pairs of points is the same. Section formula 2 1 m m pb pa consider any two points ax1 y1 and bx1 y2 and assume that p x y divides ab internally in the ratio m1.
Sep 25 2020 collinearity of three points section formula and areas of triangles class 10 science class 10 notes edurev is made by best teachers of class 10. Section formula a point pxy which divide the line segment ab in the ratio m 1 and m 1 is given by the mid point p is given by area of triangle abc area of triangle abc of coordinates ax 1y 1 bx 2y 2 and cx 3y 3 is given by for point ab and c to be collinear the value of a should be zero. Slope formula method to find that points are collinear.
Find the point on the x axis which is equidistant from a 34 and b 1 4. This video explains the concept of collinear points by using the formula of the area of a triangle. Ab bc and ac.
