What is the name of a 8 sided polygon?
What is the name of a 8 sided polygon?
octagon
A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… There are names for many different types of polygons, and usually the number of sides is more important than the name of the shape.
What is the interior angle of a 8 sided shape?
1080 degrees
The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees.
What is the interior angle of a 9 sided polygon?
140 °
To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .
What is polygon with 8 sides called?
An 8-sided shape is called an octagon. Any time that a shape is a polygon, and it has eight sides, we call it an octagon. Besides, is an octagon any shape with 8 sides?
What type of Polygon has 8 sides?
The octagon is also a type of polygon that has 8 sides as well as 8 angles. The octagon is composed of two words – octa and gonia. In which, octa refers to eight and gonia means angles.
What is the regular polygon of 8 sides called?
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t {4}, which alternates two types of edges. A truncated octagon, t {8} is a hexadecagon, {16}.
What does a 8 sided polygon look like?
An octagon is an 8-sided polygon (a flat shape with straight sides). First, have a play with an octagon: When all angles are equal and all sides are equal it is regular, otherwise it is irregular
