The vertices of a

Answer :


Given, coordinates of vertices A(-1, 3) B(1, -1) and C(5, 1)


Let the median through the vertex C is CM, where M is the mid-point of AB. [As median bisects the base of a triangle]


To find : length of CM


Also, mid-point of a line joining coordinates A(x1, y1) and B(x2, y2) are



Coordinates of M


M = (0, 1)


By using distance formula, distance between two points (x1, y1) and (x2, y2) is


d = √(x2 - x1)2 + (y2 - y1)2


As, C = (5, 1) and M = (0, 1)


CM = √(5 - 0)2 + (1 - 1)2


CM = √(5)2


CM = 5 units
