FAQ: What Is Enlargement In Geometry?

Enlarging a shape changes its size. A transformation is a way of changing the size or position of a shape. To enlarge a shape, a centre of enlargement is required. When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.

What is enlargement and reduction in geometry?

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. Dilation Reduction. If the scale factor is greater than 1, the image is an enlargement.

How do you describe an enlargement?

When describing enlargements you must state by how much the shape has been enlarged. For example, a scale factor of means that the side-lengths of the new shape are twice the side-lengths of the original. A scale factor of means that the side-lengths of the new shape are three times the side-lengths of the original.

What is an enlargement factor?

The size of an enlargement/reduction is described by its scale factor. For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original.
