What are examples of parallelograms?
In geometry, a quadrilateral is called a parallelogram. A parallelogram has its opposite sides parallel and equal in length. Few examples of a parallelogram are rhombus, rectangle, and square.
What are common parallelograms?
They all have the properties of a parallelogram: Their opposite sides are parallel, their diagonals bisect each other and divide the parallelogram into two congruent triangles, and opposite sides and angles are congruent.
Is Diamond a parallelogram?
A parallelogram in which all the edges are of equal length is called a rhombus, or a diamond. In addition to the general properties of parallelograms, in a rhombus, the diagonals bisect the angles, and the diagonals are perpendicular to each other.
What is the most special type of parallelogram?
Rectangle. A rectangle is a special type of parallelogram which has all the properties of parallelogram along with some different properties. Each angle of a rectangle must be a right angle, i.e. of 90°.
What is the most special kind of parallelogram?
There are three special types of a parallelogram.
- Rhombus: A parallelogram in which all sides are equal. Here AB = BC = CD = DA.
- Rectangle: A parallelogram in which all angles are right angles and the diagonals are equal.
- Square: A parallelogram with all equal sides and all angles equal to 90 degrees.
What is the most special parallelogram?
The biggest distinguishing characteristics deal with their four sides and four angles. A rectangle is a parallelogram with four right angles. A rhombus, which is sometimes called a rhomb or diamond, as Math is Fun nicely states, is a parallelogram with four congruent sides.

What is a unique parallelogram?
In a parallelogram, opposite sides are equal, opposite angles are equal and diagonals bisect each other. A quadrilateral can be constructed uniquely if its two adjacent sides and three angles are given. • A quadrilateral can be constructed uniquely if its three sides and two included angles are given.
Which is not a special 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 are all the parallelograms?
Parallelograms are four-sided shapes that have two pairs of parallel sides. Rectangles, squares and rhombuses are all classified as parallelograms. The classic parallelogram looks like a slanted rectangle, but any four-sided figure that has parallel and congruent pairs of sides can be classified as a parallelogram.
What are the four properties of a parallelogram?
Properties of Parallelogram : The following are the four important properties of parallelogram. 1. The diagonals of a parallelogram bisect each other. 2. In a parallelogram, the opposite angles are congruent. 3. In a parallelogram, the opposite sides are equal. 4. In a parallelogram, the opposite sides are parallel.
What shapes are not a parallelogram?
If only one set of opposite sides are congruent, you do not have a parallelogram, you have a trapezoid. This means every parallelogram is: A plane figure (it has two dimensions) A closed shape (it has an interior and exterior) A quadrilateral (four-sided plane figure with straight sides)
What is always true about a parallelogram?
It is always true. A parallelogram is a quadrilateral where opposite sides are parallel. So a quadrilateral ABCD is a parallelogram if and only if AB is parallel to DC, and BC is parallel to AD. The angles between side AB and adjacent sides AD and BC are supplementary (their measures add up to .
