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.
Special Right Triangles. 30-60-90 Triangles. An equilateral triangle is a triangle with all sides congruent. From the Isosceles Triangle Theorem if follows that the angles of an equilateral triangle are all the same. Since the angles of any triangle add to 180 o, each angle of an equilateral triangle must be 60 o.n equilateral triangle is a triangle with all sides congruent.
