multiple similarity transformations are performed on a triangle. which elements must be preserved?\norientation\nside length\nangle measure\noverall size
Answer
Brief Explanations:
Similarity transformations include dilation, rotation, reflection and translation. Dilation changes side - lengths and overall size, and rotation and reflection change orientation. But angle measures are preserved in similarity transformations.
Answer:
C. angle measure
