## What is a symmetry of a heart?

The heart is symmetrical because there is symmetry in its design. This heart can be divided in half vertically where one half matches the other half. This line that divides the heart into matching parts is called the line of symmetry. You can determine other lines of symmetry by looking at other objects.

## What is the line of symmetry of a heart?

Fold the heart to show a line of symmetry. There is only one line of symmetry in this heart shape.

**What is symmetry line?**

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. A square has 4 lines of symmetry, as shown below.

**How many lines of symmetry does this shape have?**

Regular Polygons

An Equilateral Triangle (3 sides) has 3 Lines of Symmetry | |
---|---|

A Square (4 sides) has 4 Lines of Symmetry | |

A Regular Pentagon (5 sides) has 5 Lines of Symmetry | |

A Regular Hexagon (6 sides) has 6 Lines of Symmetry | |

A Regular Heptagon (7 sides) has 7 Lines of Symmetry |

### Does a heart have rotational symmetry?

A shape has rotational symmetry when it still looks the same after a rotation. There’s the shape rotated 90 degrees counterclockwise. This shape, this heart, does not have rotational symmetry.

### How many sides do a heart have?

Muscular walls, called septa or septum, divide the heart into two sides. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs. On the left side, the left atrium and ventricle combine to pump oxygenated blood to the body.

**How do you draw symmetry?**

You can practice symmetry in drawing by practicing with a mirror. Draw a straight line using a ruler either on the vertical or horizontal axis. On one side of the straight line draw half of a shape. For example, draw half of a cross or heart shape.

**How should we draw a line of symmetry give two examples?**

One more good example is to imagine if we cut an equilateral triangle into two equal halves, then the two triangles formed after the intersection is the right-angled triangles. Few more examples such as square, rectangle, circle, can also be considered for line symmetry.

#### How to explain the symmetry of the heart?

Explain that the piece of yarn, which marks where you held the mirror and made the proper fold, represents the heart’s line of symmetry. Refer back to the butterfly image and show how the butterfly’s line of symmetry runs vertically down the middle of its body.

#### Can a shape have more than one line of symmetry?

In an Asymmetrical figure, none of the sides of the shape is equal. You cannot fold the heart further to get the perfect symmetry. Hence, we can say that the heart-shape has one and only one line of Symmetry. There are some figures wherein the lines of symmetry can be more than one.

**How to check symmetry in a construction paper heart?**

Let your students know that the next activity will involve using a mirror to check figures for symmetry. Model the checking process before having students begin the activity. Hold up the construction paper heart, then hold up a mirror across its center to reflect its left half.

**How are the alphabets divided vertically in symmetry?**

Some of the alphabets such as A, H, M, O, U, V, W, T, Y can be divided vertically in symmetry. The symmetry line or horizontal axis of a shape which divides the shape into two identical halves is known as horizontal line of symmetry. That means the axis here crosses across the shape to cut it into two equal parts.
