it depends on what kind of shape it is. an equilateral triangle has 3 lines of symmetry, yet a sqaure has 4. (both shapes i mentioned are regular polygons)
16 * * * * * Not sure what a rectangular octagon is but no kind of octagon has more than 8 lines of symmetry.
A polygon is a 2-dimensional closed figure that has at least three sides. A pentagon is a 2-dimensional closed figure that has five and only five sides, so it is a kind of polygon.
The letter "D" has only one line of symmetry, going horizontal across the letter.

It is not a polygon, because a polygon is a closed figure.
you mean like this kind of design 101
An EQUILATERAL Triangle. Two lines of symmetry is ISOSCELES Triangle No lines of symmetyry is SCALENE Triangle.

It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.
A square has both parallel and perpendicular symmetry. It is composed of two sets of parallel lines that meet at perpendicular angles.
A quadrilateral is a4-sided figure with no congruent sides.
