In general, a triangle can have 0, 1 or 3 lines of symmetry.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.

The line that divides a square into two equal parts is called the diagonal. The diagonal of a square is a line segment that connects two opposite vertices of the square. It is also the longest possible line segment that can be drawn within the square, dividing it into two congruent right triangles.
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.
