Question

When applied to a triangle, a dilation with a positive scale factor does not preserve __________.
A.angle measure
B.orientation
C.shape
D.length

Answer 1

I believe it is D. If anyone can verify that it'd be appreciated.

Answer 2

Correct. Dilation means to become larger. The size changes. That means the side lengths become larger. Since the triangles are similar, the angle measures remain the same.
