How many lines of symmetry does a triangle have? The number of lines of symmetry a triangle has depends on the type of triangle. An equilateral triangle has three lines of symmetry, while an isosceles has one line of symmetry, and a scalene triangle has none.
An equilateral triangle is an isosceles triangle as it has 2 lengths that are equal and 2 equal sized angles. An isosceles triangle does not necessarily have to have equal lengths and angles do not have to be 60 degrees. So an equilateral triangle is an isosceles triangle but an isosceles triangle may not always be an equilateral triangle.
