## How many triangles are there in a regular polygon of 20 sides?

There are 20c3= 1140 ways to choose three vertices that form a triangle. Of these, there are 20 triangles with two side lengths on the perimeter of the regular polygon. Also, for each side, there are 16 points that can make a triangle with exactly one side length on the 20-gon.

## Is there a 9 sided shape?

In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

## What’s a 8 sided shape called?

octagonIn 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}.

## Are triangles convex?

A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape. Think of it as a ‘bulging’ polygon. Note that a triangle (3-gon) is always convex.
