u dont use a formula
you just times it by two
a) two different squares
parallelograms have two sets of parallel lines trapezoids do not
A square and a rhombus are two special forms of parallelograms.
No.
If two parallelograms are similar then the corresponding angles are EQUAL.
It is sometimes true that two parallelograms are similar. The could be congruent, or dissimilar in that one is not an enlargement of the other.
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.
