Yes, and its opposite sides are always equal and its opposite angles are always equal. The angles and the sides can be any size.
A parallelogram always has four sides.
No. A quadrilateral only must have four sides; those four sides can be arranged on any angle that permits the four sides to also have four angles.
No, because all four sides need not be the same length.
No, only sometimes. If a parallelogram has four equal sides, then it's also a rhombus, and could also be a square. Otherwise, it's just a parallelogram, and has only two pairs of equal sides.
A parallelogram is a shape with four sides e.g square.
A parallelogram always has four sides.
A square has four equal sides. A parallelogram can also have four equal sides, but not always. (A square is also a type of parallelogram, but not the only one that can have four equal sides.
No, a parallelogram is not always a trapezoid, but they are both four-sided quadrilaterals. A parallelogram has two pairs of parallel sides, and a trapezoid has only one pair of parallel sides.
No. A quadrilateral only must have four sides; those four sides can be arranged on any angle that permits the four sides to also have four angles.
a rectangle has four right angles and opposite sides are all the same length This means that a parallelogram is not always a rectangle, but a rectangle is always a parallelogram, by definition.
By definition, a parallelogram has four sides. There is no other type of parallelogram.
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle.
No, because all four sides need not be the same length.
No, only sometimes. If a parallelogram has four equal sides, then it's also a rhombus, and could also be a square. Otherwise, it's just a parallelogram, and has only two pairs of equal sides.
Four of each.
A parallelogram with four congruent sides may be either a square or a rhombus.
A rhombus is a parallelogram because it is a four sided rectilinear figure where opposite sides are parallel but a parallelogram is not always a rhombus.
