In order for JKL to fall on the shaded triangle there needs to be a sequence of transformations. So it would be a translation of down 1 and reflection of y-axis
Because the shape JKL was rotated about the origin....where if you draw a line from point K(3,4) to the origin and another line from the origin to the image point of K...which is (-4,3)....;and the angle between the two lines is 90 degrees
And if you try it with any point...J and L...to their images...(-8,3) and (-4,7) respectively...it should still produce a 90 degree angle at the point O
