Question

Question 2
Q2) Write the coordinates of points (i) AC
(ii) B.D
​

Answer 1

Answer:

A(2,2). C(1,0)

B(4,-1). D(-2,3)

Answer 2

Co-ordinates of point A :- ( 2,2)

Co-ordinates of point B:- ( 4,-1)

Co-ordinates of point C:- (1,0)

Co-ordinates of point D :- (-2,3)

___________________

The exact location of a point on a plane is presented or depicted in the form of (x, y) . Here x and y are known as the coordinates of the point.

Abscissa :- It lies on x- axis ( horizontal line )

Ordinate :- It lies on y - axis ( vertical line)

Cartesian plane is divided into four quadrants :-

Quadrant 1 :- (+x, +y)

⟹ In Quadrant 1 both abscissa and ordinate are positive.

Quadrant 2 :- (-x, +y)

⟹ In Quadrant 2 abscissa is negative and ordinate is positive.

Quadrant 3 :- (-x, -y)

⟹ In Quadrant 3 abscissa is negative and ordinate is also negative.

Quadrant 4 :- (+x, -y)

⟹ In Quadrant 4 abscissa is positive and ordinate is negative.
