A parallelogram with four right angles is a rectangle. It may also be a square,but not necessarily-- only if the sides are also of equal lengths
No, all sides are UNEQUAL. Nope, all different. All sides equal would be equilateral which means "equal sides"
A parallelogram where all sides are equal is a square.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
No.

Perimeter of a parallelogram = 2 (A + B) 'A' and 'B' are the lengths of any two adjacent (touching) sides.

A parallelogram where all sides are equal is a square.
A regular pentagon has 5 equal sides. An irregularpentagon has 5 sides that are not all equal.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
A rhombus has all sides equal and opposite sides parallel. This includes a square which is a special case of a rhombus with all angles equal (90 degrees) as well. If opposirte sides are equal but not all sides are equal, it is a parallelogram
No. The opposite sides are always equal to each other. All sides are equal only if it is a square or rhombus.
A triangle in which all sides are of equal length is an equilateral triangle.A triangle in which two sides are of equal length is an isoceles triangle.A triangle in which all sides are of different length is a scalene triangle.
3 equal sides = equilateral 2 equal sides = isosceles all sides different = scalene
No.
A Square has 2 sets of parallel sides and 4 congruent sides.
