Points on a Cartesian Plane
Define abscissa and ordinate.
Let ABCD be a square of side 2a. Find the coordinates of the vertices of this sqaure when
(i) A coincides with the origin and AB and AD are along OX and OY respectively.
(ii) The centre of the square is at the origin and coordinate axes are parallel to the sides AB and AD respectively.
The ordinate of a point is twice its abscissa. If its distance from the point (4, 3) is , then the coordinates of the point are
(1, 2) or (3, 6)
(2, 1) or (6, 3)
(2, 1) or (3, 6)
(1, 2) or (3, 5)
If 'a' is the length of one of the sides of an equilateral triangle ABC, base BC lies on x-axis and vertex B is at origin, find the coordinates of the vertices of the triangle ABC.
