A parallelogram
A rectangle has two sets of two equal sides and four right angles.
It will have 4 sides
A rhombus or a parallelogram
A parallelogram has two sets of parallel sides. It can have four sides that are equal in length. That is why a square is also a parallelogram. You can have a parallelogram with two sets of parallel sides, all of which are equal in length, but they do not meet in right angles. It looks kind of like a lopsided or squished square, and it is called a rhombus.
Yes. A square has two sets of equal and parallel opposite sides. All four sides and all four angles (right angles) are equal.
A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
a square
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
Yes it is. Also, there has to be 2 sets of equal length sides. Of course, there is 2 sets of sides with equal length every time unless it is a square.
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
