## What is the best definition of a parallelogram?

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

## What is parallelogram define with example?

A flat shape with 4 straight sides where opposite sides are parallel. Also: • opposite sides are equal in length, and. • opposite angles are equal (angles “A” are the same, and angles “B” are the same) NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!

## What are the 4 types of parallelograms?

The four basic properties of parallelogram are: Opposite sides of a parallelogram are equal. Opposite angles of parallelogram are equal. Diagonals divide the parallelogram into two congruent triangles. There are three special types of parallelogram, they are:

- Rectangle.
- Rhombus.
- Square.

## How do you identify a parallelogram?

To identify a parallelogram, the shape has to meet one of the following criteria:

- It has two pairs of parallel opposite sides.
- It has two pairs of equal opposite angles.
- It has two pairs of equal and parallel opposite sides.
- Its diagonals bisect each other.

## What is a real life example of a parallelogram?

Real life examples of parallelograms include tables, desks, arrangements of streets on a map, boxes, building blocks, paper and the Dockland office building in Hamburg, Germany.

## Can a parallelogram have right angles?

Right Angles in Parallelograms In a parallelogram, if one of the angles is a right angle, all four angles must be right angles. If a four-sided figure has one right angle and at least one angle of a different measure, it is not a parallelogram; it is a trapezoid.

## How do you prove a parallelogram?

Well, we must show one of the six basic properties of parallelograms to be true!

- Both pairs of opposite sides are parallel.
- Both pairs of opposite sides are congruent.
- Both pairs of opposite angles are congruent.
- Diagonals bisect each other.
- One angle is supplementary to both consecutive angles (same-side interior)

## What type of angles has a parallelogram?

A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles “a” and “b” add up to 180°, so they are supplementary angles. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!

## What shape is not a parallelogram?

An ordinary quadrilateral with no equal sides is not a parallelogram. A kite has no parallel lines at all. A trapezium and and an isosceles trapezium have one pair of opposite sides parallel. A Concave quadrilateral or arrowhead does not have parallel sides.

## What shape is a parallelogram but not a square?

Lesson Summary. A rhombus is a quadrilateral (plane figure, closed shape, four sides ) with four equal- length sides and opposite sides parallel to each other. All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares.

## Which is not parallelogram?

So, from the above definitions it is clear that trapezium is not a parallelogram, as for being a parallelogram each pair of opposite sides must be equal and parallel. Note: Remember that square, rectangle and rhombus are parallelograms while kite and trapezium are not.
