How many lines of symmetry are there for an equilateral triangle

The line of symmetry is the line that passes through the object's or shape's center.

It is regarded as the object's axis or imaginary line.

You must have studied about the term symmetry in geometry class, which is described as a balanced and proportionate likeness observed in two halves of an object, with one half being the mirror image of the other.

Now, let's find the lines of symmetry in the equilateral triangle.

See the equilateral triangle above which has all three sides equal and all three angles equal showing 3 lines of symmetry.
