Sonia created a symmetrical design plain. For a group activity of class ix b, the teacher divided the space as a cartesian plane and chairs are placed at various points for the group of four students at points a,b,c and d. I) now we have to find the length.
A cartesian plane (named after french mathematician rene descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: A point in the plane's cartesian coordinates are expressed as (x,y). Here we have the figure placed on a cartesian coordinate plane with all the verticles representing different points in the coordinate plane.
