2. This is the original shape which is a rectangle dimensions are 6cm by 4cm. The first step is , we need to see that when we multiply each dimension by a fixed number what will be happening to the dimensions and the area of this rectangle.
3. We conclude that each dimension will be enlarged by the same number. We call this number the scale factor. We conclude that the (New Area) = ( Old Area ) x (Scale factor) 2
4. The conclusion of our investigation that all shapes are simliar by The angles still equals ( 90 degree ) All sides are in proportion = S.f [ S.f = Scale Factor ] . i.E The scale factor is the same 4/3 = 8/6 = 12/9 = 2/1.5 = 4/3
