A regular hexagon has a perimeter of 50m. What is the length of its side? The perimeter of a Regular Hexagon: A regular hexagon is a type of polygon. It has six numbers of sides having an equal length and equal angle. The sum of the six numbers of side length is k...
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram. Which is a closed curv...
A regular hexagon has an area of 963. What is the length of each side of the hexagon? Area of a regular hexagon: We need to understand a few properties of a regular hexagon: 1. In a regular hexagon, all sides equal the same length and all i...

Decagon: A decagon is a 10-sided polygon. Dodecagon: A dodecagon is a 12-sided polygon. Equilateral Triangle: A triangle in which all three sides are of equal length. In such a triangle, the angles are all equal as well. Equilateral Triangle: A triangle in which all three sides are of...
We know that the angle of an n sided regular Polygon is equal to ( 2 n − 4)/n right angles. Let θ be the angle of a regular decagon. Then, θ = ( 2 × 10 − 4)/10 = 8/5 right angles ∴θ = ( 8/5 × 90 )^@ = 144^@ [∴ 1 right angle =
Sum of interior angles of polygon View Solution The exterior angle of a regular polygon is one-third of its interior angle. How many sides has the polygon? View Solution Prove that the interior angle of a regular pentagon is three times exterior anles of a regular decagon. View Solution ...
