Can a shape have rotational symmetry and line symmetry?
Yes. Any equilateral shape can have both rotational and line symmetry.
What figure has symmetry if there is a rotation of 180 degrees or less that maps the figure onto itself?
Any shape with a rotational symmetry of order 2 or more.
Which shape line of symmetry but no rotational symmetry?
A semicircle.
Does a shape have to be a regular polygon in order to have rotational symmetry?
A line segment would have rotational symmetry.
Is a 180 degree rotation a reflection for a regular shape?
Not always. It depends where the line of symmetry is located.
Does a Heart have rotation symmetry?
A real life heart will not, but if you're talking about the cartoon/picture heart, then yes it will. <3
Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a line of symmetry?
Yes, that's correct. Rotational symmetry refers to the property of a shape that remains unchanged after a certain degree of rotation around a central point or axis. The number of times a shape fits within a full rotation without changing appearance is its order of rotational symmetry.
What type of figure is rotational symmetry?
Rotational symmetry is when you turn or rotate a shape and it still looks the same. A circle is the most common answer. However, it you rotate a square about 90 degrees, it still looks the same, so it is considered rotational symmetry. Technically, any shape can have rotational symmetry because it you rotate it 360 degrees, it still looks the same.Definition of rotational symmetry:Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted. The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex. It can not be the same side or vertex.
Can a shape have rotational symmetry and line symmetry?
Yes. Any equilateral shape can have both rotational and line symmetry.
What is the order of rotational symmetry for a regular hexagon?
The order of rotational symmetry for a shape is the number of times that it can be rotated so that it appears the same without rotation (e.g. if you rotate an equilateral triangle 60o clockwise it looks the same).For regular polygons, the order of rotational symmetry for the shape is the number of sides that it has. A hexagon has 6 sides so has order of rotational symmetry 6.
What shape has order of rotational symmetry but no lines of symmetry?
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
What figure has symmetry if there is a rotation of 180 degrees or less that maps the figure onto itself?
Any shape with a rotational symmetry of order 2 or more.
What shape has a rotational symmetry of order 1?
none shapes have 1 rotational symmetry because in rotational symmetry one is none
How much rotational symmetry does triangle have?
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
Which shape line of symmetry but no rotational symmetry?
A semicircle.
What shape has a line of symmetry and rotational symmetry?
circle
What shape has a rotational symmetry of 120 degree?
An equilateral triangle, and all regular polygons with 3n sides.
