    Can you name the points of the parent image and its corresponding points in its image?

    Can you mark the corresponding points in the image as \(D^/\), \(E^/\) and \(F^/\)

    Hmm let's see... Can you mark them in the diagram... ? (click on the top right corner pencil of the drawing I posted last) I'll show how to get the corresponding point of D which is \(D^/\)
