Question

3) The image of triangle DEF is triangle D'E'F'.

Which transformation will the triangles NOT be congruent?

Answer 1

dilation with a scale factor of 3/2, centered at origin

Explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformations that preserve the shape and size of an object. That means that they produce an image which is congruent to the object. Examples of rigid transformation is rotation, reflection and translation. Dilation is not a rigid transformation because it does not preserve the shape and size of the object.

All the transformation of the triangle will be congruent except the dilation with a scale factor of 3/2, centered at origin.
