If a regular polygon has n sides, then each exterior angle is given by exterior angle= (360°)n. ~~~(2.1) ~ Method ~1 Extend the common edge PO to point T as shown below. The angles labelled x°, y° and z° are exterior angles of the regular decagon, regular heptagon and regul...
A shape is regular if and only if it is both equilateral and equiangular—that is, if and only if all the sides have the same length and all the angles are equal. The “regular” version of any polygon is the most elite, most symmetrical version possible of that polygon. The “regular...
To find the interior angle of a regular polygon, divide the sum of the interior angles by the number of sides. A. True B. False 13 not attemptedThe sum of the interior angles in a decagon (a 10 sided polygon) is 1440°.What is each internal angle in a regular decagon? A. 144...
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...

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...
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...
This is the same regardless of how many sides the polygon has. The exterior angles of a triangle add up to 360°; the exterior angles of a decagon also add up to 360°. Exterior Angle Sum of a Polygon = 360 degrees Suggested Reading ...
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 =
