A parallelogram belongs to the class of shapes named as quadrilaterals because it has 4 sides.
Geometric shapes formed from three or more straight lines (polygons) include:3 sidestriangle4 sides (quadrilaterals)square (4 equal sides, right angles)trapezoid (4 sides with only 1 set of parallel lines)rectangle (4 sides with 2 sets of parallel lines)rhombus (4 sides, 2 parallel pair)5 sides - pentagon6 sides - hexagon7 sides - heptagon (rarely septagon)8 sides - octagon9 sides - enneagon (classically - nonagon)10 sides - decagon11 sides - hendecagon (classically - undecagon)12 sides - dodecagon (classically - duodecagon)13 sides - tridecagon or triskaidecagon14 sides - tetradecagon15 sides - pentadecagon16 sides - hexadecagon17 sides - heptadecagon18 sides - octadecagon19 sides - enneadecagon (nonadecagon)20 sides - icosagon*For a list of some other basic shapes, see the related link.

A trapezoid is a 4 sided quadrilateral
Spacecraft, spherical, crystal, and cylinder , and these are the 4 basic shapes of virus

sqare, circle oval, and rectangle!
x+5, y+4
it has 4 sides but the basic shapes tend to be a square, rectangle and kite
Squares have 4 90 degree angles and 2 sets of parallel lines and 4 congruent sides. A rectangle has the angles and parallel lines. A parallelogram has the parallel lines. A rectangle is most similar, however there are more geometric shapes with some similarities to a square.

geometric mean of 4 and 25=√(4x25)=√100=10
4, -1236, -108 is not a geometric system.
