A parallelogram is a quadrilateral having two pairs of opposite sides parallel to each other. To draw a parallelogram, make two lines that are parallel to each other and the same length, and then draw two more parallel lines of equal length connecting them into a four-sided shape.Continue Reading
A parallelogram can be drawn in countless different ways. As long as it has four vertices (which are the angles where the lines meet), four lines, two pairs of parallel lines of equal length and four angles whose sum is 360 degrees, the shape is considered to be a parallelogram. Squares, rectangles and rhombuses are also considered to be parallelograms according to this definition. It is important to note that, because the opposite sides are parallel and equal in length, the opposite angles also are equal. Rulers and protractors help greatly when drawing parallelograms.
The angles of the different lines of parallelograms are always supplementary, meaning that their sum equals 180 degrees. The word "parallelogram" comes from the Greek word "parallelogrammon," which indicates a shape drawn with parallel lines. Not all quadrilaterals are parallelograms. For example, the trapezoid does not meet the requirements to be considered a parallelogram because it only has one pair of parallel sides that are not always equal in length.Learn more about Shapes
