The word symmetry is the most commonly used concept in the study of reflections of mages. It is often referred to as mirror or reflective symmetry; that means a line or plane that can be drawn through an object such that the two halves are mirror images of each other.

Symmetry is ...a)-when one shape is exactly opposite of another shapeb...
Explanation:
Symmetry is the concept of balance and proportion. When we talk about symmetry in shapes, we mean that the shape looks the same on both sides.
Types of Symmetry:
There are three types of symmetry:
1. Reflectional Symmetry: When a shape can be reflected over a line and still look the same, it has reflectional symmetry. This is also known as line symmetry.
2. Rotational Symmetry: When a shape can be rotated around a central point and still look the same, it has rotational symmetry.
3. Translational Symmetry: When a shape can be translated (moved) without changing the way it looks, it has translational symmetry.
Answer:
The correct answer to the question is option 'B'. When one shape becomes exactly like another if you flip it, it is called reflectional symmetry or line symmetry. This means that if you draw a line down the center of the shape, the two halves will be identical.
For example, a square has four lines of symmetry, one for each side. If you cut a square in half diagonally, the two pieces will be identical. That is why a square has reflectional symmetry.
Similarly, a circle has infinite lines of symmetry because it looks the same no matter where you draw a line through it.
In conclusion, symmetry is an important concept in mathematics and art. It helps us understand balance and proportion in shapes and designs. Reflectional symmetry is one type of symmetry where a shape looks the same on both sides when flipped over a line.
