Question: What Is Parallelogram In Math?

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:

  1. It has two pairs of parallel opposite sides.
  2. It has two pairs of equal opposite angles.
  3. It has two pairs of equal and parallel opposite sides.
  4. Its diagonals bisect each other.

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!

  1. Both pairs of opposite sides are parallel.
  2. Both pairs of opposite sides are congruent.
  3. Both pairs of opposite angles are congruent.
  4. Diagonals bisect each other.
  5. 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.
