For example, the rectangle body shape is defined as a "boyish" body type - your hips, waist, and bust are about the same size. Then you'll get the information what your body shape is. All you need to do is to measure your bust, waist, hips and high hip, and type the values into the tool. If you are wondering which shape your figure is most similar to, check out our body shape calculator. One of the most searched for problems connected to rectangles is body shape type.

You could think that the world would be easier to draw if every country would be rectangle. Also, in a circle calculator, you'll find a dedicated paragraph about the roundness of the countries with a similar table and examples. If you're interested in the topic, you can have a look at this explanation and discussion of the results. How is it even possible, to be rectangular and round at the same time?! As you can guess, it's all about the definition of rectangularity and roundness, which may not be adequate for complex or scattered shapes - and the borders of countries are usually such examples, containing sharp edges, small islands or colonies somewhere on the other part of the globe. The confusing thing is that the 2nd most rectangular country - Vatican - is at the same time the 4th-roundest country, and Poland, 5th in roundness classification, is 9th in the rectangularity ranking. The USA is in the middle of the ranking, mainly because of eccentricity of Alaska and Hawaii. RankĮgypt is the leader, but that shouldn't surprise anybody checking the shape of that country on the map. Barry's web page, as the image of the world below. Index of 1 - a perfect rectangle, 0 - an infinite number of infinitely small islands. Highest scores from rectangularity ranking. Have a look at the table below and check out the first ten countries, as well as the least rectangular ones. He found out that the most rectangular country is Egypt, whereas the "least rectangular country in the world" title goes to the Maldives (however the author admits that calculations for countries that consist of many small islands could be terribly wrong). But have you ever wondered who's the winner of the most rectangular country competition? An Australian geo-statistician David Barry calculated the parameter of rectangularity for all countries in the world, and he created a ranking. Many different rankings exist, evaluating the countries - whether by their areas, populations, level of education or Nobel prize winners. Every rectangle is a trapezoid and a rectangle is a special case of a trapezoid.Every rectangle is a parallelogram and a rectangle is a special case of a parallelogram.Every square is a rectangle and a square is a special case of a rectangle.įor the other two figures we can state analogically:.So if the shape is above our shape of interest - like square and rectangle - we can say that: There are three figures connected directly to the shape: a square, a parallelogram, and an isosceles trapezoid.
#Area of a rectangle formula how to#
How to read this diagram? Let's start from our rectangle. Wondering if a square is a rectangle or a rectangle is a parallelogram? Have a look at the picture and you shouldn't have any doubts about the relations between quadrilaterals any more: Is a rectangle a quadrilateral? YES, of course.Only if it's a square (the sides of the rectangle are all equal length). Is a rhombus a rectangle? In general - NO.Only if it's a square (the angles of the rhombus are all 90 degrees). Is a rectangle a rhombus? In general - NO.concerning the revolution of a rectangle - along the side or diagonal to get a cylinder or a cone, respectively. You can think of your own properties as well e.g. The sides of the shape are parallel to the diagonals. Lines joining the midpoints of the sides of a rectangle form a rhombus, which is half the area of the rectangle.In a rectangle with the different side lengths (simply speaking - not a square), it's not possible to draw the incircle.The intersection of the diagonals is the circumcenter - a circle exists which has a center in that point, and it passes through the four corners.Other lesser known rectangular properties: the opposite sides of a rectangle are parallel to each other and have equal length.You can find the length of the diagonal, using the Pythagorean theorem. has two diagonals, which bisect each other.has two lines of reflectional symmetry - vertical and horizontal through the center.is rectilinear - its sides meet at right angles.is equiangular - all its corner angles are equal to 90 degrees.is cyclic - meaning that all corners lie on a single circle.Rectangles have many interesting properties.
