The word Pentagon is made up by joining two words \u201cPenta\u201d meaning five and \u201cgon\u201d meaning angles. This gives us the literal meaning of the word Pentagon, which is, five angles or a polygon with five angles.<\/p>\n<p>Therefore, the number of sides of Pentagon: 5<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Pentagon_Shape\"><\/span>Pentagon Shape<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A Pentagon is a polygon made up by joining five lines such that a geometrical shape is formed with five sides and five interior angles. The Pentagon can be of different types depending on the sides, angles, and Vertices.<\/p>\n<p><strong>Different types of Pentagon are:<\/strong><\/p>\n<ol>\n<li>Regular and Irregular Pentagon<\/li>\n<li>Convex and Concave Pentagon<\/li>\n<li>Equilateral Pentagon<\/li>\n<li>Cyclic Pentagon<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"1_Regular_and_Irregular_Pentagon\"><\/span>1.

But if the measurements of the sides and angles are not equal, then the Pentagon is said to be an Irregular Pentagon.<\/p>\n<p><strong>Perimeter of the Regular Pentagon<\/strong><\/p>\n<p>A Regular Pentagon contains five equal sides. Therefore, it is easy to find the perimeter of such polygons.<\/p>\n<p>Let the five sides of the regular Pentagon be A, B, C, D, and E. As the sides are equal, therefore, we can assume them to be equal \u2018S\u2019 units.<br \/>\nTherefore , Side A = B = C = D = E = S<\/p>\n<p>The Perimeter of the polygon is the total boundary of the shape. Therefore, the perimeter of the Pentagon is the sum of all its sides.<\/p>\n<p>Therefore,<br \/>\nPerimeter of a Regular Pentagon = A + B + C + D + E<br \/>\n= S + S + S + S + S<br \/>\n= 5S<\/p>\n<p>It implies that the perimeter of the Regular Pentagon is five times the length of either of its sides.<\/p>\n<p>Also, we can divide the area of the Pentagon into five equal triangular areas. Therefore we can say that the total area of a Regular Pentagon is five times the area of a single triangle formed.<\/p>\n<p style=\"text-align: center;\"><a title=\"Foundation CBSE 8\" href=\"https:\/\/infinitylearn.com\/online-courses-cbse-class-8\" target=\"_blank\" rel=\"noopener\"><strong><button>Enroll in Class 8 CBSE Foundation Classes<\/button><\/strong><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Convex_and_Concave_Pentagon\"><\/span>2.
