Maths

Similarity and enlargement

The image has a greater area than the object and has a different orientation

The image has a greater area than the object and has the same orientation

The image has the same area and has the same orientation as the object

The image has the same area as the object and has a different orientation

Which of the following options best describes an enlargement of scale factor -1?

Which of the following options best describes an enlargement where the scale factor is less than -1?

Which of the below images show a correct enlargement of scale factor -1, about the given point?

Which of the below images show a correct enlargement of scale factor -2, about the given point?

An enlargement only ever makes a shape bigger

Negative enlargements change the orientation of the image

The angles in the object and image are always the same

The area of the image will change if the scale factor is not -1 or 1

Which of the following statements is incorrect?

Fill the gap: if the scale factor of an enlargement is ____________ 1, then the image is larger than the object.

Fill in the gap: if the scale factor of an enlargement is __________ 1, then the image is smaller than the object
