How many sides does a pentagon and octagon have?
Other Types of Polygons
| Polygon | Number of Sides |
|---|---|
| Pentagon | 5 |
| Hexagon | 6 |
| Heptagon | 7 |
| Octagon | 8 |
How many sides are a octagon?
eight-sided
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}.
Does an octagon have 10 sides?
Hence, a polygon with 10 sides is known as decagon….A polygon having 10 sides is called: A. Octagon. B. Decagon. C. Dodecagon. D. None of these.
| Shape | Number of sides |
|---|---|
| Octagon | 8 |
| Nonagon | 9 |
| Decagon | 10 |
| Undecagon | 11 |
What are pentagon shapes?
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.
How many angles does a pentagon have?
A pentagon has five sides. A regular pentagon has no right angles (It has interior angles each equal to 108 degrees). An irregular pentagon has at most three right angles, because a fourth would leave 180 degrees to be used for the final angle that is (540 degrees – 360 degrees), which is a straight line.
What are the angles of a pentagon?
A regular pentagon has Schläfli symbol {5} and interior angles are 108°. A regular pentagon has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°).
How many degrees are in a pentagon?
The regular pentagon is the middle is 108 degrees at each inward angle. The Isometric triangles on the outside are 72 degrees on the base and 36 degrees at the top. If you joined all five corners of the star, it would also form a regular pentagon.
How much sides does a pentagon have?
A polygon has as many angles as it has sides. For example, a triangle has 3 sides and 3 angles. A pentagon has 5 sides and 5 angles. An octadecagon has 18 sides and 18 angles!
