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.

If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.

A trapezium has just the 1 line of symmetry.
Is it possible for a triangle to have two lines of symmetry?
No, it's not. Reflecting a triangle about *any* line has to move at least one corner (if all three stayed in place, they'd all have to be on a line, which is impossible). If the line is a line of symmetry, the result should be the same triangle, which means that the corner got moved to another corner. Reflections don't change angles, so the angles at two corners are equal. If there are TWO lines of symmetry, there's two DIFFERENT pairs of equality between the angles: angle A equals angle B, and angle B equals angle C. But then, a third pair of equality has to exist: angle A must equal angle C. This means the triangle is equilateral, and has three lines of symmetry! So the only way for the triangle to have two lines of symmetry is for it to have three.
