When you enlarge a shape, all the lengths of the sides of the shape increase in the same proportion. This is called the scale factor. All the angles in the shape stay the same size.
When you describe an enlargement you must give:
- The scale factor of the enlargement.
- The position of the center of the enlargement
The picture above shows you how an enlarged shape looks like. This one is a triangle. Unlike tessellating shapes, you can enlarge any shapes to any size.
The opposite of enlargement is reduction.
