Patterns

#### SYMMETRICAL FIGURES:

Figures through which a line can be drawn to divide them into two equal halves are called symmetrical figures.

#### COMPLETING HALVES:

Look at one half of the shapes shown here and observe how they look on being completed.
Tiling Patterns
• You must have seen beautiful patterns made of titles on the floor and bathroom walls in many buildings
• Tiles are of various shapes. Some are square in shape, some are rectangular, while some are in the shape of a triangle
• The colours used for the tiles create different patterns, with the same shapes.
• Some tiles have six sides. We can completely cover the floors by using tiles without leaving any gaps in between the two tiles.
Numbers And Patterns

Numbers also have patterns. Let us see

• We know that numbers from which we can make pairs are called even numbers
• The numbers which are not even are odd numbers
• When we add 2 odd numbers or 2 even numbes, the sum is always an even number
• When we add 1 odd and 1 even number, the sum is always an odd number
• Example:
```3+3=6(odd+odd=even)8+2=10( even+even=even)7+10=17(odd+even=odd)
```
Patterns In Numbers
• Numbers arranged in a series follow a pattern
• If we find the pattern in a series, we can write more numbers in the same series
• 1, 3, 5, 7, 9, 11, _, _, _
• Here, we see that each number is an odd number, and the next number is 2 more than the previous number
• So, the next 3 numbers will be 13, 15, and 17.
