Rectangles are often tall and slender. They are not extremely curvaceous, have a pronounced waist, and a flat bottom. Rectangles have an elegant appearance that many find appealing.

They are one of the most common body shapes - estimated to make up approximately 45% of the population. Men are more likely to have **a larger percentage** of **their weight** in the form of muscle, while women tend to have more fat and less muscle mass.

The average man weighs about 180 pounds (82 kg) and is about 5 feet 11 inches (1.80 m) tall. The average woman weighs about 115 pounds (53 kg) and is about 5 feet 4 inches (1.50 m) tall.

There are two main types of rectangles: endomorphic and ectomorphic. Endomorphs have stocky bodies with **large bones** and heavy muscles that store energy slowly. They tend to be found in sports such as football, wrestling, and boxing. Ectomorphs have **thin bodies** with small bones and tight muscles that use energy quickly. They tend to be found in gymnastics, dancing, and acting. Both endomorphs and ectomorphs tend to hold themselves against the wall when they walk.

A rectangle is a four-sided polygon having two sets of parallel, congruent sides and four interior angles of 90 degrees each. If you have a form that fits that criteria, it is also all of these things: a planar figure. A rectangle can be any size, but the most common sizes are 30 by 40 inches (75 by 100 cm), which is often called a standard sheet of paper, and 16 by 32 inches (40 by 80 cm), which is called a standard office desk pad.

There are many ways to describe the properties of a rectangle. The best way is to use mathematics to prove that it is indeed a rectangle. There are several methods used in geometry to prove that certain figures are equivalent to one another or not. In **this case**, we will use the fact that rectangles are the only figures that have **two pairs** of **opposite angles** that are equal. By using this property along with some simple math, we can conclude that whatever shape has these same angle pairs must be a rectangle.

Here are the two pairs of angles that define a rectangle: Two opposite angles are equal. And two other opposite angles are equal. This means that if you were to draw lines from each corner of this figure to any point on its surface, those lines would always cross at right angles, or 90 degrees, away from each other. These are very important properties for a rectangle to have.

If you have a form that fits that description, it is also all of the following: Figure of a plane figure with four straight edges and four right angles. A box.

There are many ways to identify if something is a rectangle. You can use **your mind** or you can use software. There are even websites that will identify shapes for you. Here are the most common methods:

1 Use your Mind. Think about what a rectangle looks like and then draw some lines on a piece of paper. Repeat this process with other objects (such as squares or circles) and see which one feels most familiar.

2 Calculate Dimensions. The dimensions of a rectangle are its length and width. To find the dimensions of a shape, simply divide the length by the width and multiply it by itself. So, for example, if the length of a rectangle is 8 inches and its width is 4 inches, its dimension score would be 2 times 2 or 4. Squares and rectangles with **same dimension score** are considered equal in size.

3 Measure from Point-to-Point. One way to know if you have found the right thing is to check whether the measurements you get are the same.
