that depends on the triangle. if the triangle has no two sides that are the same length, then it is called a scalene triangle and it has no lines of symmetry. if the triangle has two sides that are the same length, the triangle has one line of symmetry, starting at the angle where the two same length sides meet, and ending at the center of the opposite side. if all three sides are the same length, the triangle has three lines of symmetry, between any angle an the center of the opposite side.
