# Understanding Special Parallelograms in Geometry

In geometry, a parallelogram is a two-dimensional figure that has two sets of parallel sides and four right angles. While the basic definition of a parallelogram remains the same, there are many different types of special parallelograms that have additional properties and characteristics. Let's take a look at the different types of special parallelograms and examine their properties.

## Rectangle

A rectangle is arguably the most common type of parallelogram. It is composed of four sides, with two pairs of parallel lines and four 90 degree angles. All rectangles have an area of length times width, and its opposite sides are equal in length as well as parallel to each other.

## Rhombus

A rhombus is a type of parallelogram where all four sides are equal in length. This makes it easy to recognize because it looks like a diamond shape when viewed from above or below. Rhombuses also have diagonals that bisect each other at right angles, meaning they form two congruent triangles within the figure itself.

## Square

Squares are special types of rectangles where all sides are equal in length, making them both rectangles and rhombuses at once! A square's area can be calculated by multiplying any side by itself since all sides are the same size (length x width = side x side). Additionally, similar to rhombuses, squares also have diagonals that bisect each other at right angles, forming two congruent triangles within the figure itself.

## Trapezoid

A trapezoid is composed of one pair of parallel lines with two non-parallel lines on either side. Trapezoids can be classified further based on how many sides are congruent; if only one pair of non-parallel lines is congruent then it's known as an Isosceles Trapezoid, while if neither pair is congruent then it's known as an Irregular Trapezoid. The area for trapezoids can be calculated using the formula 1/2 * h * (b1 + b2) where h represents the height and b1 & b2 represent either base line respectively.

## Conclusion

Every geometric figure has specific characteristics which make them unique — those characteristics help us to identify which type of geometric figure we're dealing with when solving problems or completing assignments related to geometry! Special parallelograms such as rectangles, rhombuses, squares and trapezoids all have distinct properties which make them stand out from regular parallelograms — understanding these properties will allow students to distinguish between different geometric figures more easily when working on math problems related to shapes!

### What are the 12 quadrilaterals?

The twelve quadrilaterals are: rectangle, rhombus, square, trapezoid, parallelogram, kite, isosceles trapezoid, irregular quadrilateral; regular hexagon; convex pentagon; concave pentagon; and convex quadrilateral.

### How do you find the properties of special parallelograms?

The properties of special parallelograms depend on the type. Rectangles have two pairs of parallel lines and four 90 degree angles, with an area calculated by length times width. Rhombuses have all four sides equal in length, with diagonals that bisect at right angles to form two congruent triangles. Squares are rectangles with all sides of equal length, and trapezoids have one pair of parallel lines with two non-parallel lines on either side. The area for trapezoids can be calculated using the formula 1/2 * h * (b1 + b2) where h represents the height and b1 & b2 represent either base line respectively.
