This topic discusses the concepts of reflection and symmetry through simple examples from everyday life
Introduction to CBSE Solutions for Class 5 Mathematics: Does It Look the Same?
“Does It Look the Same?” introduces the concept of symmetry, an important part of geometry that children see in various objects around them. This chapter takes students through different types of symmetry, including line symmetry and rotational symmetry, in a simple and engaging way.
Students learn how to identify lines of symmetry in both natural and man-made objects, understand that shapes can have more than one line of symmetry, and comprehend how symmetry creates balance and harmony in designs. They are encouraged to draw symmetrical figures and patterns, which helps to improve their spatial reasoning and artistic skills.
Practical applications of symmetry are also discussed, showing how it is used in architecture, art, and nature. This chapter equips students with the ability to analyze and create symmetrical figures, laying the groundwork for more advanced mathematical concepts.

Questions and Answers for CBSE Class 5 Mathematics: Does It Look the Same?
- Q1: What is symmetry?
ANS: Symmetry is a balanced and proportionate similarity found in two halves of an object, that is, one half is the mirror image of the other half. - Q2: How many lines of symmetry does a square have?
ANS: A square has four lines of symmetry. - Q3: What is line symmetry?
ANS: Line symmetry occurs when a shape can be divided into two identical parts with a line, where one part is the mirror image of the other. - Q4: Does a circle have line symmetry?
ANS: Yes, a circle has infinite lines of symmetry because it can be divided into two identical parts in an infinite number of ways. - Q5: What is rotational symmetry?
ANS: Rotational symmetry is when an object can be rotated around a central point and still look the same at certain angles. - Q6: How do you find the line of symmetry in an object?
ANS: You can find the line of symmetry by folding the object in half. If the two halves match exactly, the fold line is a line of symmetry. - Q7: How many lines of symmetry does an equilateral triangle have?
ANS: An equilateral triangle has three lines of symmetry. - Q8: Can an irregular shape have a line of symmetry?
ANS: Yes, an irregular shape can have a line of symmetry if one half of the shape is a mirror image of the other half. - Q9: What shapes have no lines of symmetry?
ANS: Shapes with no equal halves and no lines of symmetry include scalene triangles and shapes with irregular sides. - Q10: Why is it useful to learn about symmetry?
ANS: Learning about symmetry is useful because it helps us understand geometric principles, appreciate beauty in nature and art, and it is applied in various fields like architecture, design, and technology.
