What is the scale factor of enlargement?

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

Enlargement is an example of a transformation. A transformation is a way of changing the size or position of a shape. ... When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.

How does enlargement factor work?

When enlarging a shape or image, we use a scale factor to tell us how many times bigger we want each line/side to become. For example, if we enlarged a rectangle by scale factor 2, each side would become twice as long. If we enlarged by a scale factor of 10, each side would become 10 times as long.

What is enlargement and reduction?

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 find the center of enlargement on a graph?

To find the centres of enlargement, draw lines through the corresponding corners of each shape. These lines will cross at the centre of enlargement, as shown below. The centres have been marked with the letter O in both diagrams.

What is a scale factor of 1 3?

A scale factor of 1:3 means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big.

How do you enlarge a scale factor 1 2?

2) If the scale factor is 2, draw a line from the centre of enlargement, through each vertex, which is twice as long as the length you measured. If the scale factor is 3, draw lines which are three times as long. If the scale factor is 1/2, draw lines which are 1/2 as long, etc. The centre of enlargement is marked.
