There are 20 triangles inside a 22 sided polygon
The total angles will be 3600 degrees, because each triangle will have 180 degrees total.
How many triangies make a diamond?
A polygon with 20 sides is an icosagon.
A 20 sided polygon is an 'icosagon'
There are 20 triangles inside a 22 sided polygon
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
18 triangles

20 triangles will fit into a 22 sided polygon whose interior angles add up to 3600 degrees
20 isosceles triangles with each base being a side of the 20-gon, and the opposite vertices at the center of the polygon.
A 32 sided polygon is also called a triacontadigon (or triacontakaidigon) or 32-gon has 20 triangles and 12 pentagons.
It can be divided into 18, hope this helps!
it would have 18 triangles because u take 2 away each time.
Think of the 20 identical triangles that are formed inside the polygon when you draw line segments from the centre of the polygon to each of the polygons corners. The angles of those triangles at the centre of the polygon add to 360 degrees, and there are 20 of them. Therefore, each of the angles of the triangles at the centre is 360 / 20 = 18 degrees. The angles within each triangle add to 180 degrees. Therefore the other two angles within each triangle, away from the centre of the polygon, add to 180 - 18 = 162 degrees. The two angles are equal. Therefore each angle is 162 / 2 = 81 degrees. Each interior angle of the 20-sided polygon consists of two of these angles. Therefore, the interior angle is 2 x 81 or 162 degrees.
The total angles will be 3600 degrees, because each triangle will have 180 degrees total.
Pick a point around the center of the polygon. Join each vertex to this point. You will now have 10 triangles. The total angle of these 10 triangles is 10x180 degrees. Now you need to subtract the angles of the ten triangles at the center (which is 360 degrees). Therefore total internal angles is (10x180)-360 = 1800-360 which is 1440 degrees. A 10 sided polygon has 20 internal angles. So each angle would be 1440/20 = 144/2 = 72 degrees
