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.
The two angles touching the base (which are congruent, or equal) are called base angles. The angle between the two legs is called the vertex angle. Equilateral triangles. An equilateral triangle has three equal sides and three equal angles (which are each 60Â°). Its equal angles make it equiangular as well as equilateral.
