The only shape that has 4 lines of symmetry is a square.
There cannot be a solid three sided figure. A solid 4 sided object is a tetrahedron.
A rectangle.
A 4 sided quadrilateral has 2 diagonals.
To have no symmetry the four sides would all have different lengths, and each angle would also be different. The figure would not look like a square or a rectangle, but would instead be an irregular 4-sided polygon.
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
A square has four lines of symmetry.
The only shape that has 4 lines of symmetry is a square.
A figure has rotational symmetry if it can be rotated by a certain angle (less than 360 degrees) and still looks the same. The number of times you can rotate the figure and have it look the same determines the order of rotational symmetry - a square has rotational symmetry of order 4, for example.
There cannot be a solid three sided figure. A solid 4 sided object is a tetrahedron.
the shape has 1 side of symmetry
Not all 4 sided quadrilaterals have lines of symmetry.
A rectangle.
A 4 sided quadrilateral has 2 diagonals.
To have no symmetry the four sides would all have different lengths, and each angle would also be different. The figure would not look like a square or a rectangle, but would instead be an irregular 4-sided polygon.
In 2 dimensions, a regular 5 sided figure is a pentagon. In 3 dimensions, there is no regular sided 5 sided figure. The tetrahedron is a regular 4 sided figure and a cube is a regular 6 sided figure.
Not all 4 sided quadrilaterals have lines of symmetry although some of them do have lines of symmetry.
