Which figure has line symmetry and rotational symmetry?
Many figures. For example, an ellipse.
Does a square have a plane of symmetry?
No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
A figure that has matching parts when divided by a line?
A figure that has matching parts when divided by a line is said to have a line of symmetry. These figures are also called symmetrical and their center of gravity lies along the line of symmetry.
Examples of figures with horizontal and vertical symmetry?
Square, hexagon, octagon, rectangle, bowtie-shaped figure, etc.
A line that separates figures into two matching halves is called?
A line of symmetry divides a figure into two matching halves.
How do you tell if something has rotational symmetry?
A figure has rotational symmetry if you can turn it about a figure.
If a figure has rotational symmetry does it have line symmetry?
yes
What figure has reflection symmetry and line symmetry?
square
What is a figure that has point symmetry but not line symmetry?
The letters S and N have point symmetry but not line symmetry.
What geometric figure does not have a line of symmetry?
A parallelogram does not have a line of symmetry.
Is it true that a figure with no lines of symmetry have rotational symmetry?
yes
What is a rotatinal symmetry?
it is a figure that rotates around aline of symmetry
