square
Parallelogram
a square
rhombus
An equilateral shape would have equal and opposite sides.
square
It is a quadrilateral shape because it has 4 sides and it has 2 pairs of adjacent sides that are equal with 1 pair of opposite angles being equal and its diagonale are perpendicular.
Parallelogram
a square
rhombus
An equilateral shape would have equal and opposite sides.
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 shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.
Lines that form an X shape create vertical opposite equal angles
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.
Parallelogram is a quadrilateral with opposite sides both parallel and equal in length - commonly known as a rectangle.
A Kite : This is a quadrilateral having two pairs of adjacent sides equal in length.
