Yes, the capital letter N has rotational symmetry but no lines of symmetry:
A nephroid has 2 lines of symmetry.
It has 2 lines of symmetry.

A regular triangle (aka equilateral triangle) has three lines of symmetry - these are its medians, In general, a regular n-gon has n lines of symmetry.

The number of lines of symmetry in a polygon corresponds to the number of sides it has. If a polygon has n sides, then its symmetry will be n lines of symmetry and it will have one point of symmetry. A pentagon has five lines of symmetry, nonagon has 9, n-gon has n lines of symmetry, so on and so forth.
A capital N has no lines of symmetry (nor semetry).
None.
x= 5y+10 * * * * * That looks like a mistaken merge! A regular polygon with n sides has n lines of symmetry.
Yes, the capital letter N has rotational symmetry but no lines of symmetry:
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.
A nephroid has 2 lines of symmetry.
