Question

1. Write a short note on “History of coordinate geometry”
2. On the Cartesian plane, draw a circle with center at the origin and radius
5 units. Write the points with coordinates lie inside, on, and outside the circle (four
points each).
3. Plot the points A(4, 4), B(-4,4) ,C(-4,-4) , D(4,-4) on xy-plane and identify the
figure obtained by joining AB,BC,CD, and DA.

Answer 1

Answer:

History. The method of describing the location of points in this way was proposed by the French mathematician René Descartes (1596 - 1650). (Pronounced "day CART"). He proposed further that curves and lines could be described by equations using this technique, thus being the first to link algebra and geometry.
