Ghost Of Highbury:
soo sweetsh heres your answer..
first plot the triangle in a graph paper
this will make it easy for you
now lets start with the first point - A (2,2)
remember: the invariant line is the y-axis
the formula says :SF = distance of image from invariant / distance of object
therefore 1.5 = x/2 ("2" because the perpendicular distance of the point from the invariant line is 2units)
implies that x = 2*1.5 = 3
soo the co-ordinates of this point is (3,2)
repeat this method for the other points
sry for the delay once again
if any problem plz inform me
i'll try to help
thank you
good luck
byee
Ghost Of Highbury:
the answers for the other points of the triangle...
point B (5,2) will be mapped to (7.5,2)
point C (5,4) will be mapped to (7.4/4)
