a isosceles triangle has at least 1 line of symmetry but only has 9 letters

The term you're looking for is "asymmetrical." However, "asymmetrical" actually means lacking symmetry, so it does not fit your criteria. A shape with at least one line of symmetry could be described as "symmetrical," but that only has 10 letters. If you have another specific term or context in mind, please clarify!
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.
This is different in different typefaces (fonts) but in arial: o i l s v w x z all have symmetry s and z have point symmetry the others have at least one line of symmetry.
ALL letters have at least one line of rotational symmetry. However - if you mean reflective symmetry, the letters F, G, J, L, P, Q, R, S, & Z do not.
