A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
Also What is a Heptagon shape? In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon.
Likewise What is a nonagon and Decagon? Here, a 3-sided polygon is a triangle, 4 sided polygon is a quadrilateral, 5-sided polygon is a pentagon, 6-sided polygon is a hexagon, 7-sided polygon is heptagon, 8-sided polygon is octagon, 9-sided polygon is called a nonagon and a 10-sided polygon is the decagon.
Is a nonagon concave or convex? If one or more interior angles is larger than 180°, it is concave. A regular nonagon is a convex nonagon .

What does a trapezoid look like?
A trapezoid is a four-sided flat shape with one pair of opposite parallel sides. It looks like a triangle that had its top sliced off parallel to the bottom. Usually, the trapezoid will be sitting with the longest side down, and you will have two sloping sides for the edges.
What is a regular dodecagon? A dodecagon is a 12-sided polygon. … In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.

What is the difference between a dodecagon and a dodecahedron? A dodecagon is a polygon (do for two, deca for ten, “gon”) with 12 sides. A dodecahedron is a solid with 12 faces (similar to tetrahedron, 4 faces). A dodecahedron is a 3-dimensional regular solid having 12 congruent regular pentagons as its faces.
