symmetry meaning

In maths, symmetry refers to a situation where one part of a shape or object is a mirror image of the other part. This means that if you were to fold the shape along a line, called the line of symmetry, the two halves would match up perfectly. Symmetry isn't limited to lines; it can also be rotational. In rotational symmetry, an object can be rotated around a central point and it will still look the same at certain angles.

Types of symmetry

1. Reflectional Symmetry: This is the most common type of symmetry that people are familiar with. In this case, an object or shape can be divided into two identical halves by a line, called the "line of symmetry." When you fold the shape along this line, the two halves match up perfectly. For example, a rectangle has two lines of symmetry, while an equilateral triangle has three.

2. Rotational Symmetry: In this type of symmetry, an object looks the same even after being rotated by a certain angle around a central point. For example, a circle has infinite rotational symmetry because it looks the same no matter how you rotate it. A square has rotational symmetry of 90 degrees; if you turn it 90 degrees, it still looks the same.

These are the basic types of symmetry in maths, but there are also more complex types like translational symmetry (where an object can be moved or "translated" along a path and still appear the same), glide reflection (a combination of reflection and translation), and point symmetry (where an object is symmetrical around a central point).

Understanding these types of symmetry can help in solving various mathematical problems, especially in geometry and pattern recognition. It also has applications in other fields like physics, biology, and art. So, learning about symmetry not only enhances your mathematical skills but also helps you appreciate the balance and harmony in the world around you.

FAQ's

Q: What are symmetry?
A: Symmetry refers to the balanced and proportionate similarity found in two halves of an object, shape, or image. In math, symmetry often means that one shape becomes exactly like another when you move it in some way, such as flipping or rotating it.

Q: What does symmetry mean?
A: Symmetry means the quality of being made up of exactly similar parts facing each other around an axis or center.

Q: How many symmetry lines does a square have?
A: A square has 4 lines of symmetry.

Q: How many symmetry lines does a rhombus have?
A: A rhombus typically has 2 lines of symmetry if all its angles are equal. If not, then it has no lines of symmetry.

Q: How many symmetry lines does a circle have?
A: A circle has infinite lines of symmetry.

Q: How many symmetry lines does a pentagon have?
A: A regular pentagon has 5 lines of symmetry.

Q: How many symmetry lines does a hexagon have?
A: A regular hexagon has 6 lines of symmetry.

Q: How many symmetry lines does a triangle have?
A: An equilateral triangle has 3 lines of symmetry. An isosceles triangle has 1 line of symmetry, and a scalene triangle has no lines of symmetry.

Q: How many symmetry lines does a rectangle have?
A: A rectangle has 2 lines of symmetry.

Q: What is rotational symmetry in class 7?
A: In class 7, rotational symmetry is introduced as a kind of symmetry where an object looks the same after being rotated by a certain angle around a central point.

Q: How many symmetry lines in a rectangle?
A: A rectangle has 2 lines of symmetry.

Q: Symmetry class 7 worksheet?
A: In a class 7 worksheet on symmetry, you might find various exercises aimed at helping you identify lines of symmetry in different shapes, understand rotational symmetry, and solve related mathematical problems.

Q: How many symmetry lines does a parallelogram have?
A: A parallelogram generally has no lines of symmetry unless it's a special case like a rectangle or square.

Q: How many symmetry lines in a square?
A: A square has 4 lines of symmetry.

Q: Who invented symmetry?
A: Symmetry wasn't invented; it's a natural mathematical principle and concept. However, the study of symmetry has been a part of human knowledge and culture for centuries and has been formalized in various mathematical and scientific disciplines over time.
