Where does the word parallelogram come from?

What does a parallelogram look like picture?

A Parallelogram is a flat shape with opposite sides parallel and equal in length. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms !

What is an example of parallelogram?

A parallelogram is a shape with four sides, and the sides opposite each other are parallel, meaning they don’t intersect. Examples of parallelograms include squares, rhombuses, and rectangles. Circles, triangles, and trapezoids are not parallelograms .

What shape is a parallelogram?

Parallelogram: A quadrilateral with 2 pairs of parallel sides . Rectangle : A parallelogram with 4 right angles. Rhombus: A parallelogram with 4 sides with equal length .

What else can a parallelogram be called?

If we have a parallelogram where all sides are congruent then we have what is called a rhombus . The properties of parallelograms can be applied on rhombi. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid.

Is Trapezium a parallelogram?

Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms . Others define a trapezoid as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the parallelogram a special type of trapezoid .

What’s the difference between a parallelogram and a rhombus?

In a rhombus , all the four sides are equal and the diagonals intersect at 90 degrees, whereas in a parallelogram , the opposite sides are equal and the diagonals bisect each other.
