important questions from cordinate geometry class 9
Answers
Answer:
Points A (5, 3), B (–2, 3) and D (5, –4) are three vertices of a square ABCD. Plot these points on a graph paper and hence find the coordinates of the vertex C.
Write the coordinates of the vertices of a rectangle whose length and breadth are 5 and 3 units respectively, one vertex is at the origin, the longer side lies on the x-axis, and one of the vertices lies in the third quadrant.
Plot the points (x, y) given by the following table:
x 2 4 -3 -2
y 4 2 0 5
4. Plot the following points and write the name of the figure obtained by joining them in order:
P(– 3, 2), Q (– 7, – 3), R (6, – 3), S (2, 2)
5. Locate the points (5, 0), (0, 5), (2, 5), (5, 2), (–3, 5), (–3, –5), (5, –3) and (6, 1) in the Cartesian plane.

Answer:
exercise 3.3 from NCERT
NCERT have only simple question that not help you tenth ok so try to make Questions from Rd Sharma and other high level books .....
I post some questions that baised on to find area of parallelogram in Cartesian graph .... if you have doubt so follow me I will follow you back ..... and I will help to solve Question ok!!
