How many lines of a reflectional symmetry does a equilateral triangle have?

Equilateral triangle has 3 Reflection symmetry.

Step-by-step explanation:

Given  : Equilateral triangle.

To find : How many lines of a reflectional symmetry does a equilateral triangle have.

Solution : We have given a  equilateral triangle.

Equilateral triangle :triangle which has all three sides and angles are equal.

Reflection symmetry : If we reflect any shape of figure it gives same shape .

Therefore, Equilateral triangle has 3 Reflection symmetry.
