What is a pentagon, how is the pentagonal area calculated? The following article of Software will help you define as well as find the most standard pentagonal calculation formula.
A pentagonal is a polygon with 5 sides or 5 corners. There are 2 types of pentagons: regular pentagonal (equal sides and angles) and irregular pentagonal (unequal sides and angles).
Calculate the area of the side equilateral pentagonal equal to a, irregular edge
The calculation of the pentagonal area is quite complicated, relatively difficult to remember compared to other types of shapes such as squares, rectangles, rhombuses… So you need to find the easiest way to remember or have your own tips.
HOW TO CALCULATE THE PENTAGONAL AREA
+ Calculate the area of regular pentagon:
To calculate the area of the regular pentagon, you need to know the kite is 5 sides long. From there, applying the formula for calculating the area above will produce the final result.
+ Calculate the irregular pentagonal area:
If the problem requires calculating the area of a pentagonal but not a regular pentagon, you can apply the following:
– Connect 2 of the 5 vertices of the pentagonal to form 2 shapes: 1 triangle and 1 quadrangle.
– Calculate the area of triangles and quadrangles based on the data of the article given, then add the 2 results to produce the area of the pentagon.
If you do not remember how to calculate the area of quadrangles and triangles , you can refer to other articles of Software.
The pentagon shape can make you think of some names like the Pentagon or the 5-pointed star, the starfish … In fact, the formula for calculating the pentagonal area is also quite commonly applied to calculate the area of objects and cubes.
Above is our guide to help you calculate the area of the pentagon, even or irregular. In case you need to solve geometry problems or calculate the area of a certain plane, please apply the above formula.
