# How do you know if a figure has symmetry?

draw line down the middle and fold over without overlap

or

point mirror down centre point and see if there is same shape

### How do you know that a figure does not have rotational symmetry?

When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't

### How do you tell if something has rotational symmetry?

A figure has rotational symmetry if you can turn it about a figure.

### How do you know if a figure has rotational symmetry?

Visual inspection. It's usually pretty obvious.

### When does a figure have rotational symmetry?

A figure has rotational symmetry when it has 2 lines of symmetry. Wait, that's wrong. It's 2 or more lines of symmetry. Hope this helps!! =D

### 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.

### How many orders of symmetry does a rectangle have?

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.

### Can an irregular octagon have 3 lines of symmetry?

If it is irregular most likely not. I know it is possible to have 2 lines of symmetry but I'm not so sure about 3 lines. Maybe you can figure it out by drawing it for yourself.

### Is an octagon a line of symmetry?

An octagon is a 2-dimensional figure, not a line of symmetry. However, it has several lines of symmetry.

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

A rectangle is one of them

### Which figure has line symmetry and rotational symmetry?

Many figures. For example, an ellipse.

### What is a linear symmetry?

It is called line symmetry when we can actually draw a line down the middle of a figure that divides the figure into two mirror images.

### How many lines of symmetry does the figure below appear to have Of a heart?

If the figure is an image of a real heart, then there are no lines of symmetry. If it is an idealised heart, then 1.

### How do you find the smallest angle of rotational symmetry for a figure?

If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:

### 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.

### What is axis of symmetry?

What is axis of symmetry? the axis of symmetry is a line that divides a planar figure into two congurent reflected halves

### 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.

### How could you use symmetry to find side lengths and angle measures of a geometric figure?

The answer will depend on the figure, the type(s) of symmetry and what information about is is given.

### How can you tell if a figure has rotational symmetry?

You turn it a quarter to see if it still has a line of symmetry.

### Which figure has exactly four lines of symmetry?

A square has exactly four lines of symmetry.

### What is the greatest amount of lines of symmetry a figure can have that is known?

a circle has infiniti lines of symmetry

### 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 figure has rotational symmetry but not line symmetry?

A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.

### What plane figure has one horizontal symmetry and one vertical line of symmetry and has rotational symmetry?

A rectangle is a possible candidate, as is an ellipse.

### How many lines of rotation of symmetry does a square have?

Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.

### What is the definition of reflectional symmetry?

An image has Reflectional Symmetry if there is at least one line which splits the image in half so that one side is the mirror image of the other. Reflectional symmetry is also called line symmetry or mirror symmetry because there is a line in the figure where a mirror could be placed, and the figure would look the same.

### How many line of symmetry does a pentagonal pyramid have?

There are no lines of symmetry in a 3d figure. The right question is how planes of symmetry are there in a pentagonal pyramid. Then the correct answer is 5 planes of symmetry.

### What is an axis of symmetry?

An axis of symmetry is any of one or more lines about which a geometric figure is symmetrical.

### What is linear symmetry?

A figure has linear symmetry when after reflection, the image looks exactly the same as the original

### A line that divides a figure into 2 matching parts when it is folded?

A line of symmetry, or axis of symmetry.

### Does the number 6 have a line of symmetry?

When referring to the figure and shape of "6", no it does not have any lines of symmetry.

### Which figure has line symmetry and point symmetry?

There are infinitely many such shapes. To start with, any regular will do.

### How many lines of symmetry does the figure have?

That will depend on the shape of the figure which isn't named

### What geometric figure has only one line of symmetry?

Only One Line of Symmetry An isosceles triangle only has one line of symmetry.

### What does line of symmetry mean?

line of symmetry is divides a figure into halves are the mirror images ofeach other

### What is the definition of Horizontal Symmetry?

This is my own definition of horizontal symmetry (no source)- Symmetry to describe a figure that is symmetrical after being reflected over a horizontal line.

### What is the property of a figure that can be reflected across a line so that the image coincides with the pre image?

The property is Reflection Symmetry, Line Symmetry or Mirror Symmetry

### Does every figure have a line of symmetry?

Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.

### Necklace with a symbol on it It is round and has two lines of symmetry Does anyone know how to find this symbol and figure out what it means?

you mean like this kind of design 101

### 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.

### What figure has exactly three lines of symmetry?

An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
