Yes, but not a straight line.

No, but it looks like it. Actually the leter S does have a line of symmetry. Not vertically but horizontally. See, S.

If the letter P represents the perimeter, and the letter s is representative of the length of each side, then 4s, or the product of the size length and the number of sizes refers to a square.
a square starts with 's'
How about a square or a sector of a circle.
The number of lines of symmetry in the letter "s" is zero. A line of symmetry is a line that divides a shape into two mirror-image halves, and the letter "s" does not possess this property in any orientation.
septahedron
The shape you're looking for is "seesaw." It has 11 letters, possesses at least one line of symmetry, and starts with the letter "s." A seesaw can be symmetrical along its central axis.
A shape that begins with the letter "S" and has one line of symmetry is a "star." Specifically, a five-pointed star has one line of symmetry that can be drawn through its center, dividing it into two mirror-image halves. This line bisects the star from one point to the opposite point.
