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.
opposite angles of all parallelograms are always equal.
they are not
Yes, Rectangles are always parallelograms
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
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.
u dont use a formula
No,they are not similar
no
opposite angles of all parallelograms are always equal.
they are not
no
