Question

is there a polygon which has only two types of interior angles 120 or 60 or both​

Answer 1

Answer:

Can two or more types of regular polygons be put together to tessellate a plane?

4 Answers. A regular polygon can only tessellate the plane when its interior angle (in degrees) divides 360 (this is because an integral number of them must meet at a vertex). This condition is met for equilateral triangles, squares, and regular hexagons
