Uses of coordiante geometry?

Hi Meghna,

You used the coordinate plane in algebra for graphing and solving equations. This powerful tool is also used in studying geometry. Although the idea of graphing on a coordinate plane dates all the way back to the 1600's, it didn't appear in our high school math textbooks until the early 1900's. Since that time it's become more and more important for solving different types of math problems.

We can graph lines, line segments, rays, and angles—as well as other geometric figures—on the coordinate plane and use the graphs to help us determine their relationship to each other as well as other features such as length.

Here's one way geometry is used in the real world. A team of archaeologists is studying the ruins of Lignite, a small mining town from the 1800's. They plot points on a coordinate plane to show exactly where each artifact is found.

Please feel free to post as many doubts on our discussion forum as you can. If you find any question Difficult to understand - post it here and we will get you the answer and detailed  solution very  quickly.

All the best.
