the "base" of the triangle is one side of the polygon.We can learn a lot about regular polygons by breaking them into triangles like this: (Not all polygons have those properties, but triangles and regular polygons do). This means it has 6 sides, 6 corners, and 6 interior angles. ![]() The radius of the incircle is the apothem of the polygon. The hexagon definition states that a hexagon is a 6 sided polygon and the name is derived from a Greek word where hex means six, and gonia means corners. The "inside" circle is called an incircle and it just touches each side of the polygon at its midpoint. Regular Hexagon A regular hexagon is defined as a closed 2D shape made up of six equal sides and six equal angles. The radius of the circumcircle is also the radius of the polygon. The hexagon definition states that a hexagon is a 6 sided polygon and the name is derived from a Greek word where 'hex' means six, and 'gonia' means corners. The faces can be different shapes anywhere from a common shape like a square or rectangle. The six sides, also known as faces, are straight. The "outside" circle is called a circumcircle, and it connects all vertices (corner points) of the polygon. A hexahedron is any 6-sided, three-dimensional shape. Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: In a regular hexagon, all the sides and all the angles are equal, and so each of the interior angles measures 720°/6= 120°.Example: What are the interior and exterior angles of a regular hexagon?Īnd now for some names: "Circumcircle, Incircle, Radius and Apothem. The sum of the interior angles in a hexagon is 720°. It’s a heptahedron having seven faces, fifteen edges, and ten vertices. A prism with a pentagonal base is known as a pentagonal prism. … Similarly, hexagons are polygons with six sides. A cube is a solid three-dimensional object having six square faces, facets, or sides, three of which meet at each vertex. Hexagons are two-dimensional shapes that can be regular, irregular, concave, convex, or complex. In geometry, a hexagon is a six-sided polygon with six interior angles that amount to 720°, and six exterior angles that sum to 360°. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers. What shape has 6 sides not a hexagon?Ī five-sided shape is called a pentagon. Because the hexagon is regular, all of the interior angles will have the same measure. What do the interior angles of a 6 sided shape add up to?Įxplanation: The sum of the interior angles of a hexagon must equal 720 degrees. Therefore, the measure of exterior angle becomes 180° 135° 45°. Each interior angle of a regular octagon is equal to 135°. A regular octagon will have all its sides equal in length. Each equilateral triangle has a length of 8 units. In simple words, the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. Is a hexagon an equilateral?Ī hexagon is made up of 6 congruent equilateral triangles. So it literally means “nine sided shape”. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. It has nine straight sides that meet at nine corners. What polygon has 9 sides?Ī nine sided shape is a polygon called a nonagon. The internal angles of a regular hexagon add up to 720 degrees. ![]() It has no curved sides and all the lines are closed. Most people often use the words hectagon and hexagon. On the other hand, a hexagon is a polygon with six edges, vertices, and angles. It is common for people to use this word when referring to hexagon, which is a mistake. The plural form of the word is hectagons. How many sides do a hexagon have?Ī hexagon is a 2D geometric polygon that has six sides and six angles. Hectagon (noun): a polygon with 100 edges, vertices, and angles. Is it a closed shape with 6 sides?Ī closed shape with 6 sides is termed as a hexagon. You may cut the six pieces and angles for a wooden hexagon on a miter saw using a custom fixture. The six-sided shape of the hexagon reduces the chance of slipping, allowing hex fasteners to be driven at high speeds by electric-power hex screwdrivers or drills without the screwdriver head stripping the screw notch. What angle do I cut to make a hexagon?Ĭutting a 60-degree angle on each end of all six pieces results in six pieces of wood that will fit together and form a hexagon. Does a hexagon have 6 equal sides?Ī regular hexagon has six equal sides and six equal interior angles. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°. In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon or 6-gon.
