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.
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.
A parallelogram has rotational symmetry of order 2.
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.

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.
The line of symmetry in a shape is found be looking at the sides of the shape. If you see that two sides look the same, try to draw a straight line through them. The line of symmetry acts like the dotted line in which you fold you paper. If you can fold the shape across the line of symmetry, and the shape is exactly the same on both sides then you have found A line of symmetry.
