Depends on the type of triangle. For a ; - Equilateral triangle - 3 lines Isosceles triangle - 1 line Scalene triangle - 0 (zero) lines. For a right-angled triangle, it can be either 1 lines or no lines, but NOT 3 lines.
No such thing as a regular triangle. You need to be more accurate in your triangular description. Equilateral triangle is symmetric about three lines of symmetry. Isosceles triangle is symmetric one line of symmetry. Right-angled, and Scalene triangles have no lines of symmetry.
0 lines of symmetry
YES!!! An equilateral triangle has three lines of symmetry. They are drawn from any one corner to the opposite base. They should all intersect at the centre of the triangle. By comparison, an Isosceles triangle has only one line of symmetry. From the one unequal angle to the opposite side. Right angled, and scalene triangles do not have lines of symmetry.
None
A scalene triangle that is not right angled.
3 lines * * * * * None if it is acute angled scalene One if it is acute angled isosceles and Three if it is equilateral.
a scalene triangle has no lines of symmetry
A scalene triangle has no lines of symmetry.

A scalene triangle
Scalene.

An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.
0 lines of symmetry
No
An EQUILATERAL Triangle. Two lines of symmetry is ISOSCELES Triangle No lines of symmetyry is SCALENE Triangle.
