which transformations are nonrigid transformations? Check all that apply. dilation reflection rotation stretch translation
Answers
A rigid transformation preserves both length and angle measurements.
We will have examples stated below.
Examples of rigid transformations are :
1) Rotation
2) Reflection
3) Translation.
Dilation — This is a transformation that produces an image with the same shape as the original image but of different size.
Stretch is also same as dilation.
They have the following characteristics.
It can be enlargement of the original image, a reduction or one that stretches the original image.
It preserves only the angle measurement.
The correct answer is thus :
Dilation and Stretch
Transformation: To manipulate the shape of a point or a line the pre-image and the final image of the point along with it's position is the transformation.
Types:
- Translation
- Rotation
- Reflection
- Dilation
- Stretch
Rigid transformation: A type of transformation where the length and the angle of the original image is preserved in the transformed image is referred to as rigid transformation.
Here,
Dilation and stretch do not modify the angle and the dimension of the original image.
Hence, Dilation and stretch is the answer.
