1.     Open Program Wingeom

2.     Draw a triangle of ABC at kuadran 1 and then typing a point of D at center point axis

3.     Click transform > rotate , type ABC at vertice

4.     Rotate the triangle of ABC, for example such that point center of D. then type D at using center. Typing the size of rotate angle 90, then the triangle of ABC will be moves as far as 90 such that point center.

5.     The triangle ABC and A’B’C’ are congruent. Look the different at the point.
