no, only equilateral triangles have 3 lines of symmetry
Different triangles may have none, one, or three lines of symmetry.
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.
because there are only THREE sides/ray.
Most triangles don't have any lines of symmetry. An isosceles triangle has one. An equilateral triangle has three.

It depends on the type of triangle: -- scalene triangles have three sides of different length, and no lines of symmetry -- isoceles triangles have one line of symmetry that includes the apex -- equilateral triangles have three lines of symmetry, all bisectors through a vertex
A scalene triangle. Though it's usually defined as having three sides of different lengths, this is an equivalent definition: all equilateral triangles have three lines of symmetry, and all isosceles triangles have one (no triangle has two lines of symmetry).
because there are only THREE sides/ray.
No, scalene triangles, which have sides of different lengths, have none. Isosceles triangles, with only two sides the same, only have one.
Most triangles don't have any lines of symmetry. An isosceles triangle has one. An equilateral triangle has three.
equilateral triangle
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.
