Question 17:

Find the coordinates of the points which divides the line segment joining and into four equal parts.

and

Let and are the points which divide line segment AB into equal parts.

Let coordinates of point and

We know .

It means, point P divides line segment AB in .

Using Section formula to find coordinates of point P, we get

Since .

It means, point Q is the mid-point of AB.

Using Section formula to find coordinates of point Q, we get

Because .

It means, point R divides line segment AB in

Using Section formula to find coordinates of point P, we get

Therefore,

Question 18:

The two opposite vertices of a square are Find the coordinates of the other two vertices.
