Which of the following situations best describes a transformation that is not an isometric transformation?

AA triangle is rotated clockwise about a point.
BA triangle is reflected over the line y = 2.
CA triangle is dilated by a scale factor of 2.
DA triangle is translated two units to the left.

Verified Answer :

C. A triangle is dilated by a scale factor of 2.

Here, "Dilation" occurs instead of Transformation of the coordinate. So, the Origin (Centre of point) would remain same

Hope this helps!

CA triangle is dilated by a scale factor of 2.
