Question

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

Answer 1

Well a equilateral triangle is a triangle with 3 sides of the same length so it would be 3.

Answer 2

In equilateral triangle there are three lines of reflection symmetry.

Further Explanation:

Triangle is defined as the three sided close figure.

Equilateral triangle is a triangle that has all 3 sides equal.

In equilateral triangles all the angles are equal and the each angle is of measure ${60^ \circ }$.

The reflection symmetry is defined as a line that divides the Figure into two equal parts.

Like a line that divides the Figure into two equal parts.

To obtain the line of symmetry mark a line from a vertex to the side opposite at the midpoint of the side.

There are three vertices in a triangle. The maximum reflection of symmetry can be obtained are three.

Reflection symmetry divides the side of the triangle into two equal parts.

Hence, in equilateral triangle there are three lines of reflection symmetry.
