A regular polygon triangle is an equilateral triangle. It has three lines of symmetry: a line passing through each vertex and the mid-point of the opposite side. These are the three medians or altitudes or perpendicular bisectors or angle bisectors of the triangle - they are all the same lines.

Which polygon has less then 4 lines of symmetry?
A triangle has 3 lines of symmetry.
How many lines of symmetry in a regular polygon?
it depends on what kind of shape it is. an equilateral triangle has 3 lines of symmetry, yet a sqaure has 4. (both shapes i mentioned are regular polygons)
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.
