18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
it would have 18 triangles because u take 2 away each time.

18 triangles
There are 20 triangles inside a 22 sided polygon
It can be divided into 18, hope this helps!

A 32 sided polygon is also called a triacontadigon (or triacontakaidigon) or 32-gon has 20 triangles and 12 pentagons.
20 triangles will fit into a 22 sided polygon whose interior angles add up to 3600 degrees
An infinite number. Just when you think you are done, pick any triangle, draw a line from any of its vertices to the opposite side and you have spilt that triangle in two. As a result the number of triangles is increased by one. You think you are done? Pick any triangle, ...
20 of them.

A 20-sided polygon, also known as a icosagon, has 20 vertices. Each vertex corresponds to a corner point of the polygon where two sides meet. Therefore, a 20-sided polygon is defined by its 20 distinct vertices.
