Option (A) "A polygon has 7 sides. No angles go inside of the shape" is correct.
<h3>What is a regular polygon?</h3>
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
As we know, a convex heptagon is a polygon with seven sides, seven internal angles, and seven vertices, which means that a convex heptagon has seven sides.
A convex heptagon is a polygon that has 7 sides. No angles go inside of the shape.
Thus, option (A) "A polygon has 7 sides. No angles go inside of the shape" is correct.
