WebApr 12, 2024 · A decagon is one such polygon that has ten sides. In this article, we will explore the properties of a decagon and how it can be constructed. Properties of a Decagon. A decagon is a ten-sided polygon with ten angles. The sum of the interior angles of a decagon is (n-2) x 180 degrees, where n is the number of sides. By joining one vertexto the remaining vertices of the decagon, 8 triangles will be formed. By joining all the vertices independently to each other, then 80 triangles (8×10) will be formed. Look at the image given below, showing diagonals and triangles of a decagon. Like other shapes, a regular decagon also … See more A regular decagon is a polygon along with10 equal sides and 10 vertices. The sides and angles are congruent in a regular decagon. The characteristics of a regular decagon are: 1. All sides are equal in length and all the … See more An irregular decagon does not have equal sides and angles. At least two sides and angles are different in measurement. Look at the images given … See more Simple decagons refer to decagons with no sides crossing themselves. They follow all of the above said regular decagon rules. While complex decagons refer to decagons that are self … See more Like any other polygon, decagons also can be convexand concave. A convex decagon bulges outward as all the interior angles are lesser than 180°. While concave decagons have … See more

WebThe basic properties of a pentagon are given below which help to identify a polygon to be a pentagon. A pentagon has 5 sides and 5 angles. 5 diagonals can be drawn in a pentagon and this can be calculated using the formula, Diagonals of a pentagon: = n × (n − 3) ÷ 2 = 5 × (5 − 3) ÷ 2 = 5. The sum of all the interior angles of a pentagon ... WebMay 3, 2024 · The correct answer gives you ( 10 2) − 10 = 35, the reasoning being that you choose two vertices of the 10 and draw a diagonal between them. However, as you said, consecutive vertices will not give a diagonal, so we ignore the 10 sides of the decagon that arise from this counting. great wall 2012
