What figure has exactly two lines of symmetry?

with corners: rectangles and rhombiwithout corners: ovals (ellipse)The diagonals are the two lines of symmetry of any rhombus that is not a square.


How many symmetry lines does a square have?

4 lines. Two from the corners and two from the middle of the sides.


What figure has two lines of symmetry and two rotations of symmetry?

A rectangle is one of them


Is a rhombus symmetrical?

Yes a rhombus has 2 lines of symmetry. These lines of symmetry join its opposite corners.


Is it possible for a quadrilateral to have three lines of symmetry?

It can't have exactly three (it can be a square and have four). Reflecting about a line of symmetry swaps at least two corners of the quadrilateral: a corner has to be symmetric to a corner, and if all four were symmetric to themselves, they'd all have to be on a line, which is impossible. Moreover, different lines of symmetry swap different pairs of corners. Once you pick two corners, there is only one line of symmetry which could possibly swap them - the perpendicular bisector of a segment drawn between the two corners. If two different corners are symmetric, that means that their angles are equal. So three lines of symmetry means that there are three pairs of corners with equal angles. Since there are only four corners total, the only way for this to happen is for all four corners to have equal angles. Then it's either a rectangle (which doesn't work - only two lines of symmetry) or a square (which has four lines of symmetry). Neither possibility has exactly three.


Can a figure with two or more lines of symmetry can have rotational symmetry?

Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.


What type of figure has two lines of symmetry?

A rectangle is one of them


What shape has four right angles but only two lines of symmetry?

A rectangle. Obviously the right angles are in the four corners of the rectangle. The lines of symmetry occur across the horizontal and vertical. There are no lines of symmetry on the diagonal.


What figure has two 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)


Can a octangon and a square make a figure with two or more lines of symmetry?

No.


How many lines of symmetry does a irregular figure have?

It depends on the irregular figure. A rectangle, for example, has two.


Can a figure have line symmetry and not rotational symmetry?

Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
