In general, a triangle can have 0, 1 or 3 lines of symmetry.
Oh, dude, it's called a diagonal. Yeah, like when you draw a line from one corner to the opposite corner of a square, that's the fancy term for it. It's like the square's way of saying, "I'm not just a boring ol' four-sided shape, I've got some flair with my diagonals."
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.

Well, honey, that sounds like a rectangle to me. It's got those four right angles, two diagonals for days, and don't forget those four axes of symmetry. So, if you're looking for a shape that fits that description, you've hit the jackpot with a good ol' rectangle.
it has 1 line of symmetry
It can have as many lines of symmetry as it has points.
In general, a triangle can have 0, 1 or 3 lines of symmetry.

The letter 'H' has 2 lines of symmetry. Hope this helped :) Coocoo1999

Six.
five, if it's a regular pentagon.
no its got infinity lines of symmetry
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
A trapezium has just the 1 line of symmetry.
Usually none. In some fonts, though, it may have a horizontal line of symmetry - half-way up.
