An equilateral triangle.
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
Equilateral triangle
An equaliateral 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.
a square has more then three lines of symmetry, but I don't think a parrellelogram with only two parallel sides can
This varies according to the polygon. A polygon is any 2D closed shape with three or more straight sides. Therefore, a polygon such as a square will have four lines of symmetry, but an irregular hexagon may have several or none. Even a triangle can have between zero and three lines of symmetry, depending on the type of triangle it is.
