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 two parallelograms are similar then the corresponding angles are EQUAL.
a) two different squares
yes * * * * * Never. A parallelogram has two pairs of equal angles opposite one another. A trapezoid does not.
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.
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.
No,they are not similar
they are not
u dont use a formula
opposite angles of all parallelograms are always equal.
Not all parallelograms are rectangles. A parallelogram is a shape with two parallel sides. Sometimes a parallelogram is a rhombus, trapezoid or a square.
