The scale factor.
Not to the square root, but to the square.

ratios
The ratios of all three corresponding sides is ALWAYS equal. But there is nothing that can be said about parts of the sides.
That is correct.

ratios
If two polygons are similar then the ratio of their perimeter is equal to the ratios of their corresponding sides lenghts?
No. In similar triangles, the ratios of the 3 pairs of corresponding sides are always equal.
The ratios of all three corresponding sides is ALWAYS equal. But there is nothing that can be said about parts of the sides.
If and when two parallelograms are similar, you know that the ratio of two side lengths within one parallelogram will describe the relationship between the corresponding side lengths in a similar parallelogram. If and when two parallelograms are similar, you know that the ratio of corresponding side lengths in the other parallelogram will give you the scale factor that relates each side length in one parallelogram to the corresponding side length in a similar parallelogram.
True
That is correct.
Corresponding angles are equal.The ratios of pairs of corresponding sides must all be equal.
If the ratios are equivalent the corresponding points will all be on the same straight line through the origin.
