Answer: The correct options are
(1) Figure A.
(2) Figure B.
(3) Figure C.
Step-by-step explanation: We are given to select the figures that are polygons.
<u>POLYGON :</u> A polygon is a plane shape with straight sides having number of sides greater than or equal to three.
In Figure 1, there are three straight sides, so it is a polygon with three sides. We call it a TRIANGLE
In Figure 2, There are four straight sides, so it is a polygon with four sides. We call it a QUADRILATERAL.
In Figure 3, there are six straight sides, so it is a polygon with six sides. We call it a HEXAGON.
In Figure 4, there is no straight side, and hence the figure is NOT a polygon.
Thus, the correct Figures are A, B and C.
Options (1), (2) and (3) are correct.
