Which figures are polygons? figure a has 6 sides all made of line segments. figure b is a regular hexagon. it has 6 sides made all of segments. figure c is shaped iike a long semicircle. the bottom is a segment. the top part is curved. figure d has 7 sides which are all segments.

A polygon is a closed figure made by joining line segments, where each line segment intersect exactry two other line segments.

A polygon is said to be a regular polygon if the sides are all of the same length.

Thus, the figures that are polygon are:

Figure A which has 6 sides all made of line segments.

Figure B which is a regular hexagon, having 6 sides made all of segments.

Figure D has 7 sides which are all segments.
