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.
Typically there are three rectangular mirrors set at 60Â° to each other so that they form an equilateral triangle. The 60Â° angle generates an infinite regular grid of duplicate images of the original, with each image having six possible angles and being a mirror image or not.
