Rectangle vs Parallelogram: A Geometry Primer 

Learning the basics of geometry can be a little daunting for students, especially when it comes to understanding the differences between shapes. In this blog post, we will cover the difference between rectangles and parallelograms in a straightforward manner that is easy to understand. Let's get started! 

A rectangle is a four-sided shape with opposite sides being equal in length and parallel to each other. All of its interior angles are right angles (90°). Rectangles also have opposite sides that are of equal length. An example of a rectangle is a square because all of its sides are equal. 

A parallelogram is also a four-sided shape but all of its sides do not need to be equal in length and none of its angles need to be right angles. While some parallelograms can have two pairs of parallel sides, it is not necessary for all parallelograms. An example of a parallelogram is a rhombus because all of its sides are equal in length and its angles are all right angles. 

When looking at both shapes, there are some similarities you can notice as well as many differences. Both shapes have four sides, two sets of parallel lines, and diagonals that bisect each other at their midpoints. However, rectangles can only have right angles whereas parallelograms can have any type of angle as long as they add up to 360° degrees total. Additionally, while rectangles must have two pairs of parallel sides, this is not necessary for all parallelograms which makes them more versatile than rectangles when it comes to creating different shapes from them.  

Conclusion

In conclusion, understanding the difference between rectangles and parallelograms can help students better understand the basics of geometry and how shapes fit together in different combinations. Rectangles have four sides with two pairs of parallel lines and all interior angles being 90° degrees; meanwhile, parallelograms need only one set or parallel lines but still need all angles to add up to 360° degrees total even if they're not 90° degrees like those found in rectangles.

FAQ

What is the difference between the area of a rectangle and a parallelogram?

The area of a rectangle is calculated by multiplying its length by its width. The area of a parallelogram, however, is calculated by multiplying the length of its base by the height.

What is the difference between rectangular and rectangle?

Rectangular is an adjective used to describe a shape that is rectangular in nature, whereas rectangle is the name of the shape itself.

What are the properties of a parallelogram?

A parallelogram has four sides, two sets of parallel lines, and angles that add up to 360° degrees total even if they are not all 90° degrees. It also has two pairs of opposite sides that are equal in length.
