it has 4 equal sides and no right angles
A rhombus is a parallelogram with 4 equal sides. Many parallelograms do not have 4 equal sides. All parallelograms have 2 pairs of equal opposite sides.
A square has 4 equal sides, 2 pairs of parallel sides and 4 right angles.
4 sides, 4 vertices, 2 equal angles, 2 pairs of equal sides
A square is a rectangle. A square is a rectangle with equal sides. A rectangle Has to have 4 right angles (and only 4 corners). A Square has the same definition (4 right angles, and only 4 corners) but all the sides have to be equal. A square is not a rhombus. A rhombus is a parallelogram with equal sides. A parallelogram has to have 4 sides (2 pairs of equal sides.) The equal sides must be parallel. A rhombus has the same definition (4 sides - 2 pairs of equal sides. The equal sides must be parallel.) but all the sides have to be equal lengths.
a square if it has 2 sets of equal sides, it is a rectangle.
A square has 4 equal sides and 4 right angles whereas a rhombus has 4 equal sides but 2 equal acute angles and 2 equal obtuse angles.
The opposite sides are equal, so 2 pairs of equal sides, or in special circumstances where they are all equal, the answer is 4 (4 equal sides makes it a rhombus, which is a special parallelogram)
A Rectangle!
a rhombus must have all 4 sides equal
A square has 4 equal sides. A rectangle has 2 short sides of equal length and 2 long sides of equal length
A square has 4 right angles, and 2 pairs of equal, perpendicular sides.
