There are 4 sides, so the polygon is a quadrilateral.
No line containing any of the sides will pass
through the interior of the quadrilateral, so it is
convex. The sides are congruent, and the angles
are congruent, so it is regular.
43.
The figure is not a polygon because there are
sides that intersect more than two other sides.
44.
There are 8 sides, so the polygon is an octagon.
There is a side such that a line containing that
side will pass through the interior of the octagon,
so it is concave. The sides are not congruent, so
the octagon is irregular.
