Question

Which sequence of transformations creates a similar but not congruent triangle

Answer 1

The correct answer is:

dilation and rotation.

Explanation:

Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.

Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

hope this helped :3

Answer 2

A a dilation and reflection

dilation will make bigger or smaller therefore it cannot be congruent
