Decagons can be classified into two types: regular and irregular. A regular decagon has all sides and angles equal, while an irregular decagon has sides and angles of different lengths and degrees. Each interior angle of a regular decagon measures 144 degrees, and each exterior angle measures 36 degrees. Understanding the properties of a decagon involves using specific formulas to calculate its area, perimeter, and the measure of its interior and exterior angles. By exploring these formulas and working through solved examples, you can gain a clear understanding of the geometric characteristics of decagons and excel in <a href=\"https:\/\/leverageedu.com\/blog\/government-exams-after-12th-science\/\"><strong>competitive exams<\/strong><\/a> such as <a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/jee-mains-mathematics-questions\/\"><strong>JEE<\/strong><\/a>, <strong>NEET<\/strong>, <a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/exam-prep-quantitative-aptitude-syllabus-for-ssc-cgl\/\"><strong>SSC<\/strong><\/a>, <a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/management-cat-exam\/\"><strong>CAT<\/strong><\/a>, <a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/mat-exam-pattern\/\"><strong>MAT<\/strong><\/a>, and various <a href=\"https:\/\/leverageedu.com\/discover\/indian-exams\/engineering-entrance-exams\/\"><strong>engineering entrance tests<\/strong><\/a>.&nbsp;<\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-definition-of-decagon\">Definition of Decagon?<\/h2>\n\n\n\n<p>A decagon is a polygon with ten sides, ten vertices, and ten angles.
