CBSE Class 7 Maths Chapter 14 Notes Symmetry

Symmetry Class 7 Notes Conceptual Facts

Symmetry; If a paper is folded in half and the two halves of the paper exactly cover each other, then the shape of the paper is symmetric.
For example:

Axis of symmetry: When a figure is folded in half then the line of fold is called axis of symmetry.
For example:

Symmetry of regular polygons:

Note: Each regular polygon has a many lines of symmetry as it has sides.

Mirror reflection symmetry: The symmetry in which one half of the shape is the image of the other.
For example:

Rotational symmetry: When an object rotate clockwise or anticlockwise about a fixed point and when it looks after some rotation by a partial turn then it is called rotational symmetry. This fixed point is known as centre of rotation.

Axis of rotation: The line of symmetry about of which an object rotates is called the axis of rotation.

Angle of rotation: The angle through which an object rotates is called angle of rotations.

• A half-turn means rotation by 180°.
• A quarter-turn means rotations by 90°.
• A complete-turn means rotation by 360°.

Order of rotational symmetry: If x° be the smallest angle through which a figure can rotate and still looks the same, then the order of rotational symmetry \(=\left(\frac{360}{x}\right)\)
For example:
(i) Order of square \( =\frac{360}{90}=4\)
(ii) Order of equilateral triangle \( =\frac{360}{90}=6\)

CBSE Class 7 Maths Chapter 9 Notes Exponents and Powers

Exponents and Powers Class 7 Notes Conceptual Facts

1. Exponents are used to express the large numbers in shorter form to make them easier to read, compare the understand.

2. When a number is multiplied by itself several times, it can be expressed in short form as under

x x x x x x x x x = x⁵ which is called exponential expression.
x is called base and 5 is exponent or power or index.

3. In general aⁿ = a x a x a x a x … n times = aⁿ

4. Properties of exponents:

5. Any number raised to power 1 gives the same number.

6. For example: 5¹ = 5, 100¹ = 100

7. A negative number raised to an odd positive integer is always negative.
For example: (-4)³ = (-4) x (-4) x (-4) = -64

8. A negative number raised to an even positive integer is always positive.
For example: (-3)⁴ = (-3) x (-3) x (-3) x (-3) = 81

9. A positive number raised to an even or odd integer is always positive.
For example:
2⁴ = 2 x 2 x 2 x 2 = 16
= 3³ x 3 x 3 = 27

10. Any number raised to power zero, it gives 1.
For example: (-5)° = 1, (1000)°= 1

11. Power 2 is also called square of.

12. Power 3 is also called cube of.

13. Laws of exponents: For any non-zero integers a and b and whole numbers m and

Perimeter and Area Class 7 Notes Conceptual Facts

1. Perimeter is the actual distance around a closed figure.

2. Perimeter of a regular polygon = Number of sides x Length of one side

3. Perimeter of a square = 4 x side

4. Perimeter of a triangle = AB + BC + CA (Sum of all sides of triangle)

5. Perimeter of a rectangle = 2 [length + breadth]
= 2(l+ b)

6. Circumference of a circle is the actual distance around it.

7. Ratio of the circumference and the diameter of a circle is a constant

8. The numerical value of π is taken as \(\frac{22}{7}\) or 3.14. (approximate)

9. Circumference of a circle = 2πr, where r is the radius of the circle.

10. Area of a rectangle = length x breadth = l x b

11. Area of a triangle = \(\frac{1}{2}\) x base x height = \(\frac{1}{2}\) x b x h

12. Area of circle = πr², where r is the radius of the circle.

13. Area of a parallelogram = base x height

14. Area of a square = (Side)² = l²
