Use MathJax to format equations. Necessary conditions for the quadrilateral to be a parallelogram are as follows (1) Opposite sides of a quadrilateral are equal. In coordinate geometry, a parallelogram is similar to an ordinary parallelogram (See parallelogram definition ) with the addition that its position on the coordinate plane is known. MathJax reference. For example, in the figure above click 'reset' and select "show diagonals' in the options menu.Using the method in Distance between two points, the diagonal AC isthe distance between the points A and C:AC=√(48−6)2+(26−7)2=46.1 Similarly the side AB can be found using the coordinates of the points A and B:AB=√(18−6)2+(26−7)2=22.5 The three verticess of a Parallelogram (3,4), (3,8), (9,8).

There are 3 coordinate points that can serve as the location of the fourth vertex. Three vertices of a parallelogram are given. L(0,4), M(6,0),N(2,4). Diagonals of a parallelogram bisect each other,let the point of intersection of diagonals be M (m,n)m = 2−2+4 = 1 and n= 2−1+3 = 1∴ m =1 and n = 1Let the Fourth vertex be D(x,y)⇒ m = 21+x =1 and n = 20+y =1x +1 = 2 and y = 2Thus x = 1 & y = 2The fourth vertex of the parallelogram is D ≡ (1,2) How do I know this? The three parallelograms correspond to adding the different coloured triangles to the original black triangle in this diagram: Thanks for contributing an answer to Mathematics Stack Exchange! So mid point of diagonal AC = mid point of diagonal BD. We have received your request successfully. Favorite Answer. So we have, Co-ordinates the point of AC, Co-ordinates the point of BD, We know diagonals of the parallelogram bisect each other.
