Some triangles do have a line of symmetry. Equilateral and Isosceles triangles have a line of symmetry. If you can fold a triangle into two equal halves, the folding line is a line symmetry.
You can flip the traced version along various lines. If the flipped shape matches the original then the that is a line of symmetry. Alternatively, if you can find a fold such that the two halves of the tracing match then the fold line is a line of symmetry.
A parallelogram has rotational symmetry of order 2.
If you canfold something in half and the two sides are identical then the fold is a line of symmetry. A circle has an infinite lines of symmetry because you can fold it in infinite places and it will always be the same. An oval has two - you can fold it the long way or the short way.
Line symmetry is another name for reflection symmetry. One half is a reflection of the other half. The line of symmetry is the line where you could fold the image and have both halves match exactly.
