## What is the relation between line symmetry and point symmetry?

a plane, point symmetry is symmetry on rotation 180º around the origin. Line symmetry is symmetry on reflection in a line, so the letter “B” has a line symmetry across a horizontal line through the middle (depending on your font) and the letter “T” has a vertical line symmetry, while the letter “H” has both.

## Which figure has line symmetry and rotational symmetry?

, it appears to be same as the original figure. So, it has rotational symmetry. Thus, we can say that a rectangle has both line and rotational symmetry. So, a triangle and a rectangle has both line and rotational symmetry.

**Which shape do not have line symmetry or rotational symmetry?**

scalene triangle

A scalene triangle – A scalene triangle has no line symmetry because it has all sides unequal in length.

**Which shape has line symmetry rotational symmetry?**

rectangle

, it appears to be same as the original figure. So, it has rotational symmetry. Thus, we can say that a rectangle has both line and rotational symmetry. So, a triangle and a rectangle has both line and rotational symmetry.

### What is the relationship between the line of symmetry and the line of reflection?

Reflection symmetry is a type of symmetry which is with respect to reflections. Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half.

### How do you determine whether a figure has line symmetry or rotational symmetry?

Possible answer: To identify line symmetry, look for a line of reflection that divides the figure into mirror-image halves. To identify rotational symmetry, think of the figure rotating around its center. The figure has rotational symmetry if a rotation of at most 180° produces the original figure.

**Which figure has line symmetry but no rotational symmetry Brainly?**

(d) A trapezium, which has equal non-parallel sides, a quadrilateral with line symmetry but not a rotational symmetry of order more than 1.

**What has one line of symmetry but no rotational symmetry?**

Solution: An isosceles triangle has only line symmetry and no rotational symmetry.

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

A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational symmetry of a shape is the number of times it can be rotated around a full circle and still look the same.

#### What is point and Line symmetry?

In a plane, point symmetry is symmetry on rotation 180º around the origin. So the letter “S” has point symmetry. Line symmetry is symmetry on reflection in a line, so the letter “B” has a line symmetry across a horizontal line through the middle (depending on your font) and the letter “T” has a vertical line symmetry, while the letter “H” has both.

**What are the types of symmetry in geometry?**

There are two basic kinds of symmetry: line or reflection symmetry, where the shape looks the same on both sides of a mirror line, and rotational symmetry, where you can turn the shape through some angle and it will look the same as before you turned it.

**What is a group of symmetry?**

In group theory, the symmetry group of an object (image, signal, etc.) is the group of all transformations under which the object is invariant with composition as the group operation.

## What is symmetry in math?

Symmetry Math definition states that “symmetry is a mirror image”. When an image looks identical to the original image after the shape is being turned or flipped, then it is called symmetry. It exists in patterns. You may have often heard of the term ‘symmetry’ in day to day life.
