Question

1) construct a trapezium PQRS in which vertices P,Q,R and S are (3,0), (7,9), (-6,9) and (-2,0)
Show this in graph paper.

2)A(2,1) , B(7,1) and C(7,4) are the vertices of a rectangle ABCD by plotting these three given points on a graph paper, find the coordinate s of the fourth vertes.
​

Answer 1

Answer:

1. Let X

′

OX an dY

′

OY be the coordinate axes. Then, the four points may be plotted as given below :

Let X’ OX and Y’ OY be the coordinate axes and mark point on it.

Here, point P(-3,2) lies in II quadrant, Q(-7,-3) lies in III quadrant, R(6, -3) lies in IV quadrant and S(2,2) lies in I quadrant. Plotting the points on the graph paper, the figure obtained is trapezium PQRS.
