A triangle has 3 lines of symmetry.
A square has four lines of symmetry!
A square or rectangle
a regular square
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
parallelogram
A rectangle (that is not also a square) or a rhombus (that is not also a square). Squares have 4 symmetry lines.
It depends on how many sides that it has and whether of not it is regular (all the lines of the polygon are of equal length if it is a regular polygon). For regular polygons, the number of symmetry lines is the number of sides if number of sides is an odd number. Otherwise, the number of symmetry lines is double the number of sides. A square has 4 sides and 8 symmetry lines; a triangle has 3 sides and 3 symmetry lines.
A circle (infinitely many). A regular polygon with 4 or more sides.
it depends on what kind of shape it is. an equilateral triangle has 3 lines of symmetry, yet a sqaure has 4. (both shapes i mentioned are regular polygons)
it has 4 lines of symmetry
2 lines of symmetry
