sometimes, a square is a parallelogram and it has all equal sides
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
yes a parallelogram is a parallelogram
because both lines are paralle so it is a parallelogram
A square is always a parallelogram. Every square is a parallelogram.
A Rhombus.
A 4 sided parallelogram is an irregular polygon

A 4 sided parallelogram is an irregular polygon
No. In a regular polygon, all sides and all angles are equal. A rhombus has four equal sides but the angles don't have to be equal, so in general a rhombus is not a regular quadrilateral or a regular parallelogram. If the rhombus happens to have four equal angles, then it is a square, which would be a regular parallelogram.

I suspect it might have to do with diet.
No. In a regular polygon, all sides are congruent, and all angles are congruent. A parallelogram doesn't satisfy either of these conditions.No. In a regular polygon, all sides are congruent, and all angles are congruent.

A parallelogram is any regular geometric shape in which two opposite sides are parallel to each other.
It depends. Strictly speaking, a semi-regular tessellation uses two (or more) regular polygons and, since neither an isosceles triangle nor a parallelogram is regular, it cannot be a semi-regular tessellation. However, a less strict definition allows non-regular components.
Yes - a square is a special case of a parallelogram in which all sides are equal length and all angles are 90o. Every square is a rectangle, a rhombus, a parallelogram, and a regular quadrilateral.
