Answer 1

Answer:

It can be observed that opposite sides of this quadrilateral are of the same length. However, the diagonals are of different lengths. Therefore, the given points are the vertices of a parallelogram.

7. Find the point on the x-axis which is equidistant from (2, - 5) and (- 2, 9).

Answer

We have to find a point on x-axis. Therefore, its y-coordinate will be 0.

Let the point on x-axis be (x,0)

(x - 2)2 + 25 = (x - 2)2 + 81

x2 + 4 - 4x + 25 = x2 + 4 + 4x + 81

8x = 25 -81

8x = -56

x = -7

Therefore, the point is ( - 7, 0).

8. Find the values of y for which the distance between the points P (2, - 3) and Q (10, y) is 10 units.

Answer

It is given that the distance between (2, - 3) and (10, y) is 10.

64 + (y + 3)2 = 100

(y +3)2 = 36

y + 3 = ±6
