no, only equilateral triangles have 3 lines of symmetry
Parallel lines are those that are equi-distant apart for their entire length, never meeting.
Maybe yes or no
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
I imagine that all of them have three straight lines.

no they do not they have to be equal so that proves there is NO lines of symmetry * * * * * It depends on the triangle. Equilateral triangles have 3 lines of symmetry, Isosceles triangles have 1 and all other triangles have none.

triangles simply does not have them. The lines in a triangle conects after a path that does not produce paralel lines.
All triangles have less than 4 lines of symmetry.
If you have 8 small triangles made of 16 lines how can you make four small triangles if it is a parallelogram?
All triangles - equilateral or not - have three straight sides.
