A kite or a parallelogram, depending on whether the equal sides are adjacent to, or opposite one another.
A parallelogram with 4 equal sides is a rhombus
It becomes a square.
Rhombuses are paralellograms. Also, they're what you might call a diamond.* * * * *Not a particularly useful answer since a rectangle is also a parallelogram. The two differences are:all the sides of a rhombus are of equal length while in a rectangle opposite sides are equal but adjacent sides are usually not equal (if they are, then the shape is a square);all the angles of a rectangle are right angles while in a rhombus opposite angles are equal but adjacent angles are usually not equal (if they are, then the shape is a square).
A parallelogram with four right angles is a rectangle; if the rectangle also has four equal sides, then it is known as a square.
No, rhombus refers to its shape, not the fact that is has four equal sides. You could call a rhombus an equilateral parallelogram by why would you want to? Also, would you then call a square a rhombic rectangle?
A parallelogram has only four sides. A five-sided figure is a pentagon. or can also be called a polygon
In Euclidean geometry, a parallelogram is a simple (non self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean Parallel Postulate and neither condition can be proven without appealing to the Euclidean Parallel Postulate or one of its equivalent formulations.A simple (non self-intersecting) quadrilateral is a parallelogram if and only if any one of the following statements is true;Two pairs of opposite sides are equal in lengthOne pair of opposite sides are parallel and equal in length.source:From Wikipedia, the free encyclopedia;Subject: Parallelogram.
A parallelogram. Example of parallelogram is a square, a rectangle, and a rhombus.
