A trapezium is a quadrilateral, which is defined as a shape with four sides and one set of parallel sides.
- The pair of parallel sides are called the bases while the non-parallel sides are called the legs of the trapezoid
- The line segment connecting the midpoints of the non-parallel sides of a trapezoid is called the mid-segment

Perfect squares end in 0, 1, 4, 5, 6, 9 only.
- 65² = 65* 65.
- Multiply 5 *5 = 25
- So, we can say that the ones place digit of the square of 65 will be 5.

A set of numbers is said to be commutative for a specific mathematical operation if the result obtained when changing order of the operands does not change the result.
- Whole Numbers
- Addition–Changing the order of operands in additionof whole numbers does not change the result. Hence, whole numbers under addition are commutative.
- 2+3 = 3 + 2
- 0 + 6 = 6 + 0
- Subtraction - Changing the order of operands in subtractionof whole numbers changes the result. Hence, whole numbers under subtraction are not commutative.
- 5-3 ≠3 - 5
- 0 - 6 ≠ 6 - 0
- Multiplication - Changing the order of operands in multiplication of whole numbers does not change the result. Hence, whole numbers under multiplication are commutative.
- 5 x 3 = 3 x 5
- 2 x 0 = 0 x 2
- Division - Changing the order of operands in divisionof whole numbers changes the result. Hence, whole numbers under division are not commutative.
- 4 ÷ 2 ≠ 2÷ 4

We have
0.25(4f – 3) = 0.05(10f – 9)
Let us open the brackets:
f - 0.75 = 0.5f - 0.45
or f - 0.5f = - 0.45 + 0.75
or 0.5f = 0.30
Dividing both sides by 0.5, we get
f = 0.6

Given x⁴ - y⁴
= ( x² )² - ( y² )²
{ Using identity
a² - b² = ( a + b ) ( a - b ) }
= ( x² + y² ) ( x² - y² )
Again using the identity
= ( x² + y² ) [ ( x )² - ( y )² ]
= ( x² + y² ) ( x + y ) ( x - y )
So, x+y a factor of x⁴-y⁴

The formula to find the number of diagonals = n(n-3)/2, where n = no. of sides of the polygon.
Here n(n-3)/2 = 35, or
n(n-3) = 70
n^2 - 3n - 70 = 0, or
(n-10)(n+7) = 0, lor
n = 10 or -7.
As n cannot be negative
Hence the figure has 10 diagonals and is a decagon.
