How many diagonals does a hexagon polygon have?
9 diagonals
Question 6 A regular hexagon has 9 diagonals.
What is the diagonal of the hexagon?
The hexagon can be broken down into 6 equilateral triangles. Each side of the equilateral triangle is equal. Two of the combined lengths of the equilateral triangles join to form the diagonal of the hexagon. Therefore, the diagonal is twice the side length of the hexagon.
How many sides does a polygon have if it has 27 diagonals?
The polygon has 9 sides.
How many triangles are determined by the vertices of a regular 24 side polygon?
22 triangles formed at each vertex by drawing 24(24–3)/2 = 252 diagonal in all. At each vertex, 21 diagonals can be drawn. 2. The sum of the 24 exterior angles = 360º.
How many diagonals are in a 25 hexagon?
A hexagon has 9 diagonals.
How many diagonals does a hexagon have 8?
(b) A regular hexagon has 9 diagonals. Here, diagonals are AD, AE, BD, BE, FC, FB, AC, EC and FD. (c) A triangle has no diagonal.
Are hexagon diagonals equal?
Explanation: Regular hexagons are comprised of six equilateral triangles; in our question, these triangles each have side length 4 (see diagram). The length of a diagonal is equal to two times the length of the side.
How many diagonals are there in a polygon hexagon?
Therefore, the number of diagonals in a polygon pentagon is 5. For n = 6, n-polygon is called hexagon and it has 9 diagonals. Therefore, the number of diagonals in a polygon hexagon is 9.
How many sides does a polygon have?
Solved Examples Polygon Name Number of Sides Number of Diagonals Quadrilateral 4 2 Pentagon 5 5 Hexagon 6 9 Heptagon 7 14
What are the properties of a regular hexagon?
Properties of a regular hexagon. A regular hexagon, just like an octagon, is a geometric figure called a polygon. It has six edges of equal length. The internal angle at each of the six vertices measures exactly 120°. The total number of hexagon’s diagonals is equal to 9 – three of these are long diagonals that cross the central point,…
How many diagonals does a decagon have?
Decagon (10 sides): n(n-3)/2 = 10(10-3)/2 = 10*7/2 = 70/2 = 35 diagonals. Icosagon (20 sides): n(n-3)/2 = 20(20-3)/2 = 20*17/2 = 340/2 = 170 diagonals. 96-gon (96 sides): 96(96-3)/2 = 96*93/2 = 8928/2 = 4464 diagonals.
