Some triangles do have a line of symmetry. Equilateral and Isosceles triangles have a line of symmetry. If you can fold a triangle into two equal halves, the folding line is a line symmetry.
A triangle has symmetry.
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:
If it is an equilateral triangle then it has 3 lines of symmetry. If it is an isosceles triangle then it has 1 line of symmetry
An isosceles triangle has 1 vertical line of symmetry
Only One Line of SymmetryAn isosceles triangle only has one line of symmetry.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
the shape is a heart.
An equilateral triangle and an isoceles triangle have one line 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.

A triangle has symmetry.
An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.
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:
If it is an equilateral triangle then it has 3 lines of symmetry. If it is an isosceles triangle then it has 1 line of symmetry
An isosceles triangle has 1 vertical line of symmetry
Only an equilateral triangle has rotational symmetry.
