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 coordinate of the vertex `C`.

Text Solution

Verified by Experts

Plot the points A(5,-3),B(-2,3) and D(5,-4). Join AB and AD. Since ABCD is a square, so all the sides are equal and each is of `90^(@)`meaure. Therefore, the absissa of the vertex C will be `-2` and ordinate `-4`. Hence, the co-ordinates of the vertex C are `(-2,-4)` .
