Example 3: Help John to find the apothem of the pentagon of the side measure 16 yards. Example 4: Peter found the perimeter of his pentagonal ground to be units. How will he find the area of the ground? A two-dimensional shape with 5 sides is known as a pentagon.
In other words, we call it a 5-sided polygon. A five-sided shape is called a pentagon. If all five sides are equal then we call it a regular pentagon, whereas if any two of the sides are different in measurement, we call it an irregular pentagon. On the other hand, a six-sided shape is a hexagon, and an octagon has eight sides. No, a pentagon is not a parallelogram , it is a five-sided polygon. A parallelogram has only four sides. A regular pentagon has 5 lines of symmetry. There is no line of symmetry for an irregular pentagon.
A regular Pentagon will have 0 parallel lines , but an irregular Pentagon can have 2 1 pair or 4 2 pairs parallel lines. A pentagon has five angles.

Difference Between Regular and Irregular Pentagons. Pentagon Examples Example 1: Sara measures the pentagon that she has drawn on the ground. The length of the thread needed will be its perimeter. Solution: Apothem is calculated if the side is known. Breakdown tough concepts through simple visuals.
Math will no longer be a tough subject, especially when you understand the concepts through visualizations with Cuemath. Practice Questions on Pentagon Shape. Explore math program. Explore coding program. Doing so shortened the distance people would have to walk from one office to another within this huge building when compared to a traditional rectangular building.
A circular building would have also incorporated shorter walking distances, but constructing a building with straight sides such as a pentagon was much easier and faster. Starfish: Almost all starfish have a fivefold radial symmetry or are shaped like pentagons. For something different, South Korea has a boy band named Pentagon. As you can see, a pentagon is a very useful shape.
Not only is a pentagon frequently used in basic geometry, it is a shape useful in architecture and found throughout the natural world. A regular pentagon has five equal sides and five equal angles.
