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.
Let's assume the triangle has points A, B, and C. Method 1 (3 lines) Draw two lines across the triangle parallel to line segment AB. Now you have two trapezoids and one triangle. Draw another line from C to the any point on the closest of the two lines you just drew, splitting the triangle into two more triangles. Method 2 (2 lines) Draw one line across the triangle parallel to line segment AB. Now you have one trapezoid and one triangle. Draw a second line that passes through C and is perpendicular to AB, splitting the trapezoid into two trapezoids and the triangle into 2 triangles. Method 3 (3 lines) Draw one line from point C to any point on line segment AB. Then draw a line parallel to AC and one parallel to BC, but don't let them cross the line you just drew.
No because the maximum lines of symmetry a triangle can have is 3 as an equilateral triangle and 1 as an isosceles triangle otherwise a triangle has no lines of symmetry.
An isosceles triangle has 1 lines of symmetry whereas a rhombus has 2; thus the rhombus has more lines of symmetry.
It depends what type of triangle it is. If it is a scalene triangle, ie. a triangle with three different length sides and angles, then it won't have any lines of symmetry. If it's an iscosoles triangle, ie. a triangle with two sides and angles of equal length, it has one line of symmetry, but if it's an equalateral triangle, ie. a triangle with all sides and angles the same, then it has three lines of symmetry.

It will have 3 lines of symmetry if its an equilateral triangle and only 1 line of symmetry if its an isosceles triangle.
Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.
Any polygon, other than a triangle, can have a pair (or more) of parallel lines.
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.

The only shape that is symmetric about a point are a circle, sphere and their multi-dimensional counterparts. There are many more functions that are symmetric about the axes or specific lines.
A triangle has only one line of symmetry but who ever says there are more than two is a idiot * * * * * A triangle, in general has NO line of symmetry, so who ever (or whoever) says there is one is and acts smart about it is a bigger idiot! That is even more so when the question is about a cone and not a triangle! What a loser! A cone, in general has no line of symmetry. A right cone has one.
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
