Question

if each side of square can be increased by 50% what would be the coordinates of the point of intersection of the diagonals?​ side 2a

Answer 1

Plot the points, A, C and D. Join them using straight lines to complete the square.

Hence B =(4,4). 

Draw diagonals AC and BD.

The point of intersection of the diagonals of a square is the mid pt of the any diagonal.

The co-ordinates of the mid-pt of a segment joining AB and CD are ((a+c)/2,(b+d)/2).

Hence, point of intersection of diagonals =(1,7)
