There are no lines of symmetry.
In this font it has two lines of symmetry.
A nephroid has 2 lines of symmetry.
Ellipses and non-square rectangles have two lines of symmetry.
A parallelagram can be a square, which has four lines of symmetry or a rectangle which has two lines of symmetry but the generic parallelagram has zero lines of symmetry
Squares, which are parallelograms, have four lines of symmetry. Rectangles have only two. Rhombi have two lines of symmetry. Generic parallelograms don't have any lines of symmetry.None normally unless it is in the shape of a rectangle in which case it will have 2 lines of symmetry
Yes. Some example of this are:Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)
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)
Rectangles and Rhombuses (have at least 2 lines of symmetry).
A four-sided quadrilateral having two lines of symmetry is a rectangle
An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
A rectangle is one of them
