In general, a triangle can have 0, 1 or 3 lines of symmetry.
Four.
A triangle has got 3 sides to it & that's why it's called a triangle. Three sides.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
5... base and one triangle on each side
Reflectional 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.
It can have as many lines of symmetry as it has points.
it has 1 line of symmetry
Four.

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

Six.
two if the triangle has a right angle
five, if it's a regular pentagon.
no its got infinity lines of symmetry
A trapezium has just the 1 line of symmetry.
