What is a shape with eight vertices called?
An octagon has eight straight sides and eight vertices (corners). It has eight angles inside it that add up to 1080°.
What is a 8 side shape?
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.
Are all 8 sided shapes octagons?
The octagon having eight congruent sides and angles is known as a regular octagon. Every regular octagon has the same angle measures. All sides are equal in length, and all the angles are equal in measure.
Which shape has more than 8 edges?
Vertices, edges and faces
| Name | Faces | Edges |
|---|---|---|
| Square-based pyramid | 5 | 8 |
| Triangular-based pyramid | 4 | 6 |
| Cuboid | 6 (all rectangles) | 12 |
| Cylinder | 3 | 2 |
How many degrees is a 8 sided shape?
1080 degrees
An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees.
What is seven sided shape called?
heptagon
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.
What shape has 10 sides?
Polygons Monogon – 1 side (degenerate in Euclidean geometry) Digon – 2 sides (degenerate in Euclidean geometry) Triangle – 3 sides Equilateral triangle – 3 equal sides Isosceles triangle – 2 equal sides Scalene triangle – no equal sides Quadrilateral – 4 sides Rectangle – 4 sides & 4 right angles Square – 4 equal sides Trapezoid Rhombus Pentagon – 5 sides
What is shape called that has nine sides?

What do you call a seventeen sided shape?

What shape has all right angles?
A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length. A rhombus is a four-sided shape where all sides have equal length.
