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.
We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60Â°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. This means that they have the same angles.
