Parallelograms are squares is that sometimes always or never true?
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.
The statement two parallelograms are similar is always never or sometimes true?
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.
What is true of rectangles that isn't true of parallelograms in general?
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
Is it true that a parallelogram is always a rhombus?
No, it's not true. A rhombus is a special kind of parallelogram, so only some parallelograms are rhombera.

All squares are parallelograms, but all parallelograms are not squares.
Are all parallelograms squares true or false?
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
