A line of symmetry for a triangle is a line along which a triangle can be folded so that either side of the line is a mirror image shape of the other.
- An Isosceles triangle, with two equal sides, has a line of symmetry from the center of the base to its opposing vertex.
- An equilateral triangle with three equal sides has three lines of symmetry, each from the center of a side to its opposing vertex.
- Any other triangle type, called a scalene triangle, has no lines of symmetry,

Do triangle contain line of symmetry?
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.
What shape has a line of symmetry?
A triangle has symmetry.
Can you show me a triangle with only one line 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:
How many limes of symmetry does a triangle have?
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
What is the symmetry of isosceles triangle?
An isosceles triangle has 1 vertical line of symmetry
