You must be talking about a rhombus.
In a rhombus, all four sides are congruent, opposite angles are congruent, and opposing sides are parallel. Rectangles, squares, and kites must be rhombi, and rhombi must be parallelograms, quadrilaterals, and polygons.
rhombus, square, rectangle, kite, parallelogram, trapezium (U.K.) trapezoid (U.S.)
They can be, but they do not have to be. A rectangle has 4 sides and 4 right angles. Which means a square, which is a type of rectangle, would have 4 of the same length sides.
A rectangle has 4 sides not the same length and 4 right angles.
Rectangle, parallelogram
The 4 sides of a square are equal in length
A square has all 4 sides the same length and its angles measure the same as well. A rhombus has all 4 sides the same length as well and the angles measure the same as well too.
A square has 4 sides that are all the same left.....duhhh!
A quadrilateral
a square
All 4 sides
It is a rectangle. Just picture it. 4 right angles and 2 sides that are the same length.
A quadrilateral
