DIlatation

Dilatation multiplication is a form of transformation is to move a point on the geometry that is dependent on the central point of dilatation and factors.

Dilatation by using Wingeom Program

1. Open The Wingeom 2 dim

2. Draw a triangle of ABC at kuadran 1, then type D at the point center axis 

3. Click transform > Dilate, type ABC at vertices

4. Type D for point center rotation at using center. Then type 90 for for angle rotation, then the triangle of ABC will be direction as point center.  Then type 2 at factor such that triangle will be zome twice.

5. The triangle ABC and A’B’C’ are congruent. Look at different in size.
