An equilateral triangle has 3 lines of symmetry
An equaliateral triangle.
A hexagon, for example, has six lines of symmetry. Three of them go to opposite vertices, and three go to opposite sides.
a square has more then three lines of symmetry, but I don't think a parrellelogram with only two parallel sides can
because there are only THREE sides/ray.
The shape that has three lines of symmetry is the equilateral triangle. It also has three angles of equal size and three sides of equal length.
An equilateral triangle has 3 lines of symmetry
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
An equallateral triangle ~ID1533681184 Sorry ID1533681184 but and equallateral triangle does not have three lines of SYMMETRY, it has three line segments. ~EEE2
An equaliateral triangle.
Equilateral triangle
Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.
If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.
A hexagon, for example, has six lines of symmetry. Three of them go to opposite vertices, and three go to opposite sides.
If you're referring to an equilateral triangle, a triangle in which all three sides are the same length, then there are three lines of symmetry.

The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
