Historically, coordinates were introduced to help geometry. And so well did they do this job that the very identity of geometry was changed. The word, oday generally means coordinate geometry In coordinate geometry. For this purpose. XOX is called x-axis or horizontal axis, YOY is called y-axis or venical axis and the point of intersection of both the axes i.
Two axes divide the plane into four regions, called quadrants. Name of the quadrant and sign of coordinates. Here, x,y is an ordered pair of "ea numbers x and.
On translation of QUI. The process of making this change called transformation of coordinates. There are basically ry types of transformations, shifting of origin translation of ate, and rotation of axes. Ifthe axes are translated a distance h to the right and a distance k upward, the origin akes new position as O h, k. Saw Leet the origin be shifted to hk.
Rotation of Axes about Origin Another type of transformation of xcs is rotation of axes, Consider point P x, y in original coordinate system ic, sy-coordinate system. Let these axes be rotated by an angle in anticlockwise direction about origin to form m system. Find the coordinates of point. What is the minimum area of a triangle with integra vertices 2. What is length of the projection of line segment joi points 2, 3 and 7, 5 on x-axis. Given the equation 4x? Through what angle should the axes be rotated so that the term xy is removed from the transformed equation?
