Question

What are the coordinates of G, H, and I after a rotation about (0,0) by 90 degrees clockwise? Plot these points on the grid, and label the, G', H', and I'. G = (-1,3) H = (-4,0) I = (3,-2)

Answer 1

Given :

Three points G ( -1,3 ) , H ( -4,0 ) and I ( 3,-2 ) .

To Find :

These points on rotating 90° clockwise about ( 0,0 ).

Solution :

Rotation of point ( h,k ) about (0,0) by 90° clockwise is ( k,-h ) .

So points :

G' is ( 3,-(-1) ) = ( 3,1 )

H' is ( 0,-(-4) ) = ( 0,4 )

I' is ( -2,-3 ) .

Therefore , rotation about (0,0) by 90 degrees clockwise is ( 3,1 ), ( 0,4 ) and ( -2,-3 ) .

Hence , this is the required solution .
