There is no way to know.
If two opposite sides are parallel and of equal length, then the quadrilateral is a parallelogram (rectangle, rhomboid, square, or rhombus).
A four-sided figure with 90-degree angles is called a rectangle. If all sides are of equal length, it is specifically known as a square. Both shapes belong to the category of quadrilaterals and have opposite sides that are parallel and equal in length.
Square
A parallelogram is a four-sided figure with opposite sides of equal length and angles not equal to 90 degrees (otherwise it would be a rectangle). Diagonally opposite angles will be equal, and adjacent angles will add up to 180 degrees.
A parallelogram is a quadrilateral with 2 pairs of parallel sides and a rhombus is a 4 sided figure (thus a quadrilateral) with all sides of equal length. Because opposite sides are of equal length opposite angles must also be equal. This angle measure defines a parallelogram.
An Octagon. ( see a stop sign ).

I Am pretty sure it's a triangle(: No it's not a triangle has 3 sides i think its a trapezoid.
