An ellipse.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
A rectangle is one of them
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)
No.
with corners: rectangles and rhombiwithout corners: ovals (ellipse)The diagonals are the two lines of symmetry of any rhombus that is not a square.
It depends on the irregular figure. A rectangle, for example, has two.
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
Square
A rectangle and a square, which is also a rectangle.
A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.
symmetry? lines of symmetry? something of the sort, i believe..why am i answering this? someone hit me
