Answer:
octagon, a regular polygon and convex
Step-by-step explanation:
The given shape has eight sides and all these shapes do not intersect each other, thus by the definition of polygons, the polygon which consists of eight sides is known as "octagon".
Also, A regular polygon is the polygon which has same sides and same angles and also the sides do not intersect each other.
Hence, the given shape is a regular polygon and also, the regular polygons are convex in nature.
Therefore, the given shape is octagon, a regular polygon and convex in nature.
