Answer 1

When you dilate a figure, the lengths of segments change according to the scale factor, but the angles remain the same. A dilated polygon is always similar to the original polygon.

Answer 2

The dilated polygon is similar tot eh original polygon.
Each side was increased by the same factor.
All angles remain the same.
Each side of the dilated polygon is parallel to the corresponding side in the original polygon.

Answer 3

Ok.
The angles remain the same.
Here is a useful postulate in geometry.
When two lines are intersected by a transversal, such that corresponding angles are congruent, the lines are parallel.
