Only equilateral triangles and some irregular polygons of (3n) sides have 3 lines of symmetry. A regular polygon with n sides (or vertices) has n lines of symmetry. If n is even, there are n/2 lines of symmetry from vertex to opposite vertex and another n/2 from the middle of a side to the middle of the opposite side. If n is odd, there are n lines of symmetry from vertex to the midpoint of the opposite side.

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.

None normally because rotational symmetry is only applicable to 2 dimensional shapes such as polygons.

The number 8 has only 2 lines of symmetry; Vertical and Horizontal.

Squares, which are parallelograms, have four lines of symmetry. Rectangles have only two. Rhombi have two lines of symmetry. Generic parallelograms don't have any lines of symmetry.None normally unless it is in the shape of a rectangle in which case it will have 2 lines of symmetry

No it has only 2
