A semi-circle is actually a specific type of shape known as a "regular" shape. A regular shape is one that has all sides and angles equal. In the case of a semi-circle, it has a curved side and a straight side, but the curved side is a perfectly round half-circle, making it a regular shape. Irregular shapes, on the other hand, do not have sides or angles that are equal.
A regular heptagon is a polygon with seven equilateral sides. The shape must also be equiangular and convex.
A sectagon is not a shape. I think you mean SEPTagon, which is a seven-sided polygon. It may or may not be regular. A regular polygon has all sides congruent and all angles congruent.
the shape is a regular shape if it has all the same angles and side lengths.
