Geometric Transformations

The following geometric transformations work for points, lines, conic sections, polygons and for images.

Mirror object at point

At first, mark the object to be mirrored. Afterwards click on the point that should be the mirror.

Mirror object at line

At first, mark the object to be mirrored. Afterwards click on the line that should be the mirror.

Rotate object around point

At first, mark the object to be rotated. Then click on the point that should be the rotation center. Afterwards a window appears where you may specify the rotation angle.

Translate object by vector

At first, mark the object to be translated. Afterwards click on the translation vector.

Dilate object from point

At first, mark the object to be dilated. Then click on the point that should be the dilation center. Afterwards a window appears where you may specify the dilation factor.
