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.
Rotational symmetry is based on points of rotation not lines
Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines of symmetry.
No.
Not necessarily, except rotational symmetry of order 1.
how many lines of symmetry has an equilateral triangle
it has only one line of symmetry.
None.
A scalene triangle that is not right angled.
A triangle........I think
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
3 lines * * * * * None if it is acute angled scalene One if it is acute angled isosceles and Three if it is equilateral.
