**How Many Lines Of Symmetry Does A Equilateral Triangle Have**. Reason for all the given polygons, having the same number of sides and the. For a triangle to have a line of symmetry, it must be an isosceles triangle, meaning two of it’s sides and two of it’s angles must be the same.

The three lines of symmetry are shown in this. It has three equal sides. Maths keeps one mentally active.

### An Equilateral Triangle Has Three Lines Of Symmetry.

Does an equilateral triangle have 180 rotational symmetry? Therefore every isosceles triangle by definition has 1. From there it follows that for a right.

### Three Angles Are Equal (60°) Three Lines Of Symmetry;

When the two sides meeting at a vertex do have the same length, the line of symmetry through that vertex passes through the. How many lines are there in isosceles triangle? A square (4 sides) has 4 lines of symmetry.

### Thus, Equilateral Triangle Has 3 Lines Of Symmetry.

When we look at the above images. Reason for all the given polygons, having the same number of sides and the. Lines of symmetryan equilateral triangle has three lines of (rotational) lateral symmetry:

### An Equilateral Triangle, Or A Triangle In Which All Of The Sides Have Equal Length, Has Three Lines Of Symmetry.

An equilateral triangle does have rotational symmetry. An equilateral triangle (3 sides) has 3 lines of symmetry. It divides the equilateral triangle into equal parts.

### A Triangle Is Only Said To Be An Isosceles Triangle If It Has 2 Equal Sides.

An equilateral triangle 3 sides has 3 lines of symmetry. It has three equal sides. An equilateral triangle has rotational symmetry of order 3.
