Question

△QRS is rotated about point P to △Q′R′S′ .

Which statements are true about the pre-image and image?

Select each correct answer.


The shape of the pre-image and the image is preserved, but the size is not.

The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved.

The image is smaller than the pre-image.

The corresponding angle measurements in each triangle between the pre-image and the image are preserved.

Answer 1

The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved.

Explanation:

As pre image is ΔQRS and image is ΔQ'R'S' . it shows that triangle is rorated at 360°. So that image is exactly same as pre image .
