Short Answer
Image completion in non-verbal reasoning often uses symmetry to identify missing parts of shapes. Symmetrical shapes are identified by checking whether one side of the shape is a mirror image of the other side. This helps in understanding balance and structure in a figure.
To identify symmetrical shapes, we observe if the shape can be divided into equal parts that match each other in size, form, and position. If both sides are identical or mirror each other, the shape is symmetrical.
Detailed Explanation:

Meaning of symmetrical shapes
Symmetrical shapes are those shapes that are divided into two equal and matching parts. These parts are mirror images of each other. In non-verbal reasoning, symmetry helps in understanding how a figure is balanced and structured.
A shape is considered symmetrical if one half exactly matches the other half when divided by a line. This line is called the axis of symmetry. The shape remains balanced on both sides of this line.
Methods to identify symmetrical shapes
Checking mirror image condition
The first method to identify symmetrical shapes is to check if one side of the shape is a mirror image of the other side.
If you fold the shape along a line and both halves match perfectly, then the shape is symmetrical. This is the simplest way to recognize symmetry in image completion problems.
Dividing shape into equal parts
Another method is to mentally divide the shape into two parts. If both parts are equal in size and shape, then the figure is symmetrical.
This division can be vertical, horizontal, or diagonal depending on the shape. The key idea is that both sides must be identical in structure.
Observing balance in design
Symmetrical shapes always look balanced. This means both sides have equal visual weight.
If a shape looks uneven or one side has extra elements, then it is not symmetrical. Balance is an important clue in identifying symmetry in non-verbal reasoning.
Types of symmetry used in shapes
Vertical symmetry
Vertical symmetry occurs when a shape is divided into left and right halves. Both halves are mirror images of each other.
This is the most common type of symmetry in image completion problems. It is easy to identify because both sides look identical when divided vertically.
Horizontal symmetry
Horizontal symmetry occurs when a shape is divided into top and bottom halves. Both parts are identical when flipped.
This type is often seen in patterns where upper and lower sections match each other in design.
Diagonal symmetry
Diagonal symmetry occurs when a shape is divided along a diagonal line. Both parts mirror each other across this line.
This type is less common and slightly more complex but important in advanced reasoning problems.
Visual clues for symmetry identification
Shape matching clues
Shapes like circles, squares, and triangles often show symmetry. By checking if parts of these shapes match, we can identify symmetry easily.
Line and structure clues
Straight lines, curves, and edges help in identifying symmetry. If both sides follow the same line pattern, the shape is symmetrical.
Repetition clues
Sometimes elements are repeated on both sides of a shape. This repetition helps confirm symmetry in image completion problems.
Importance of identifying symmetrical shapes
Improves visual reasoning
Identifying symmetry improves the ability to understand visual patterns clearly.
Helps in solving quickly
Symmetrical shapes are easier to complete, so recognizing them helps in faster problem solving.
Reduces errors
Understanding symmetry reduces mistakes in selecting wrong missing parts.
Useful in exams
Many aptitude tests include symmetry-based questions, so this skill is very important.
Conclusion
Symmetrical shapes are identified by checking mirror images, equal division, and visual balance in a figure. Vertical, horizontal, and diagonal symmetry help in understanding how shapes are structured. By using these methods, image completion problems become easier and more accurate in non-verbal reasoning.
