**4 Capital Letters Ofthe Alphabet With Rotational Symmetry** – Rotational Symmetry: A geometric shape or object is said to be symmetrical if it is divided into two or more identical pieces and arranged in an orderly manner. The property of rotational symmetry is that a shape looks the same after partial or full rotation.

The degree of rotational symmetry is the number of possible orientations in which an object appears the same for each full rotation. In this article, we will discuss symmetry especially rotational symmetry, real life examples and lines of symmetry.

Symmetry is a term used in the study of geometry, derived from a Greek phrase meaning to measure together. Two objects must have the same size and shape to be symmetrical, except that one object is oriented differently than the other. A single object, such as a face, can have symmetry.

According to the mathematical definition “Symmetry is a mirror image.” Symmetrical images, shapes or objects are similar to each other.

A line of symmetry is a line that completely divides a shape into two halves. If you fold a shape along a line of symmetry, both sides of the object or shape match exactly. The curvature of a line does not change if a mirror is placed next to it.

An axis of symmetry is a line that divides or slices a figure or object into two equal parts. An axis of symmetry is also called a line of symmetry. A line of symmetry divides a shape or object into two halves that mirror each other.

In the illustration below, the material star is folded along a line of symmetry. Every segment on either side of a line of symmetry is the same.

1. Vertical Line of Symmetry: A vertical line of symmetry separates or cuts objects, shapes or images into two equal parts downwards or upwards. A vertical line of symmetry separates or slices shapes in two directions: down and up.

Example: Cut the bottom shape vertically down as shown. On the left and right sides of a line of symmetry, the units of form are the same. As a result, a line of symmetry is formed.

2. Horizontal line: When you divide or cut any item or shape horizontally, the units produced are the same from left to right or right to left. They are called figures of symmetry, and the line of symmetry is called a horizontal line.

Example: As an example cut the shape below horizontally from left to right. The shape elements above and below the line of symmetry are the same.

3. Diagonal Line of Symmetry: It is formed when we divide or cut an object or shape into two identical parts on the diagonal. An object is cut diagonally by a diagonal line of symmetry.

Example: When the following object is divided diagonally, both sides of the diagonal (line of symmetry) are mirror images of each other. A diagonal line of symmetry is the name given to a line of symmetry.

Line Symmetry: Multiple lines of symmetry can be found in shapes or patterns, the number of times they can be folded in half and look the same on both sides.

Rotational Symmetry: When a shape or pattern is rotated or revolved around a central point, it is said to have rotational symmetry. A shape can be said to have rotational symmetry of order (X) if it can rotate around the center point (X) while remaining the same.

Since a regular pentagon has five equal sides and five lines of symmetry, its order of rotational symmetry is five. Because of its rotational symmetry, the pentagon can be rotated (5) times before returning to its initial position. Every time it rotates, it looks the same as the original position.

A rotation is a transformation that causes a preimage figure to rotate or spin to the location of the image figure. Everything else revolves around a fixed point called the center of rotation in all rotations.

This point may be inside the figure, in which case the figure remains fixed and only rotates. Alternatively, the point may be outside the figure, causing the figure to move.

The number of times you can rotate a geometric object to make it look like the original shape is called its order of rotational symmetry.

In English alphabets, rotational symmetry refers to the fact that a letter retains its appearance after being rotated. The letters (}) and (Z) are capital letters with rotational symmetry.

Answer: A square is a quadrilateral having both linear and rotational symmetry of order greater than (1.)

When a shape or pattern is rotated or twisted around a central point, it is said to have rotational symmetry. A line of symmetry is a line that divides a shape exactly in half. If you fold a shape along a line of symmetry, both sides of the object or shape match exactly. This article includes explanations about symmetry, line symmetry, rotational symmetry, order of rotational symmetry, angle of rotation, etc.

This helps in better understanding of rotational symmetry. The result of this paper helps in solving various problems based on rotational symmetry.

Answer: Rotational symmetry of a shape describes how the shape of an object remains the same when it is rotated about its axis.

Q.2. What is the order of rotational symmetry of a square? Answer: (4) is a square order of rotational symmetry.

Q.5. Which image has reflection rotation and point symmetry? Answer: A point of symmetry states that each side has a corresponding side, the same distance from the center point but in opposite directions. From the figure, only circle follows reflection, rotation and point symmetry.

Q.6. What is a line of symmetry? Answer: A line of symmetry is a line that divides a shape exactly in half. If you fold a shape along a line of symmetry, both sides of the object or shape match exactly. The curvature of a line does not change if a mirror is placed along it.
