Yes, a convex irregular 20-gon is possible. A convex polygon is defined by having all its interior angles less than 180 degrees, and it can have sides of varying lengths. As long as the vertices are arranged such that they maintain the convexity condition, an irregular shape with 20 sides can definitely be constructed.

Which of the polygons cannot be used to create a pure tessellation?
The only regular polygons which will tessellate are those with 3, 4 or 6 sides. But all irregular triangles, all irregular quadrilaterals, 15 classes of irregular convex pentagons and 3 classes of irregular convex hexagons will tessellate. In addition, there are concave polygons with different numbers of sides which will also tessellate.
Which figure can not be used as a tessellation a square or a triangle or a pentagon or a hexagon?
All of them can be used.Any triangle or quadrilateral will tessellate. There are 15 classes of irregular convex pentagons which will tessellate. Regular hexagons and 32 classes of irregular convex hexagons will tessellate. There are also concave pentagonal and hexagonal shapes which will tessellate.
