If you're referring to an equilateral triangle, a triangle in which all three sides are the same length, then there are three lines of symmetry.

How many lines of symmetry does a plolygon have?

It depends on how many sides that it has and whether of not it is regular (all the lines of the polygon are of equal length if it is a regular polygon). For regular polygons, the number of symmetry lines is the number of sides if number of sides is an odd number. Otherwise, the number of symmetry lines is double the number of sides. A square has 4 sides and 8 symmetry lines; a triangle has 3 sides and 3 symmetry lines.

That depends on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry and any other triangles have no lines of symmetry.
