A perpendicular bisector is a line segment or a ray or a line which intersects a given line segment at a 90o, and also it passes through the midpoint of the line segment. Two lines are said to be perpendicular to each other when they intersect in such a way that they form 90 degrees with each other. A bisector divides a line into two equal halves. Thus, when we talk about the perpendicular bisector of a line segment AB, it implies:
- It divides AB into two equal halves or bisects it.
- It makes right angles with (or is perpendicular to) AB.
- Every point in the perpendicular bisector is equidistant from point A and B.

Steps of construction :
1) Draw a line segment AB = 5 cm.
2) Make ∠ABC=75o. (Take 70o in place of 75o )
3) Cut off BC = 7 cm.
4) Join AC.
Therefore, △ABC is the required triangle.

Is 5/9 equal to 4/5
5/9 , 4/5
By cross multiplicatiob
= 5 × 5 =9 × 4
= 25 = 24
So, 5/9 ≠ 4/5
Hence 5/9 is not equal to 4/5

1. What is the disadvantage in comparing line segments by mere observation?
Solutions:
By mere observation we can’t compare the line segments with slight difference in their length. We can’t say which line segment is of greater length. Hence, the chances of errors due to improper viewing are more.

2. Why is it better to use a divider than a ruler, while measuring the length of a line segment?
Solutions:
While using a ruler, chances of error occur due to thickness of the ruler and angular viewing. Hence, using divider accurate measurement is possible.

LCM of 18, 24 and 32:
18 = 2 x 3 x 3
24 = 2 x 2 x 2 x 3
32 = 2 x 2 x 2 x 2 x 2
LCM = 2 x 2 x 2 x 2 x 2 x 3 x 3 = 288
The smallest four digit number that is divisible by 288:
288 x 3 = 864
288 x 4 = 1152
Since 288 is divisible by 18, 24 and 32, 1152 is also divisible by all these numbers.
Therefore, 1152 is the smallest four digit number divisible by 18, 24 and 32.

Divisibility Rule of 2
If a number is even or a number whose last digit is an even number i.e. 2,4,6,8 including 0, it is always completely divisible by 2.
Example: 508 is an even number and is divisible by 2 but 509 is not an even number, hence it is not divisible by 2. Procedure to check whether 508 is divisible by 2 or not is as follows:
- Consider the number 508
- Just take the last digit 8 and divide it by 2
- If the last digit 8 is divisible by 2 then the number 508 is also divisible by 2.
Divisibility Rules for 3
Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.
Consider a number, 308. To check whether 308 is divisible by 3 or not, take sum of the digits (i.e. 3+0+8= 11). Now check whether the sum is divisible by 3 or not. If the sum is a multiple of 3, then the original number is also divisible by 3. Here, since 11 is not divisible by 3, 308 is also not divisible by 3.
Similarly, 516 is divisible by 3 completely as the sum of its digits i.e. 5+1+6=12, is a multiple of 3.
Divisibility Rule of 4
If the last two digits of a number are divisible by 4, then that number is a multiple of 4 and is divisible by 4 completely.
Example: Take the number 2308. Consider the last two digits i.e. 08. As 08 is divisible by 4, the original number 2308 is also divisible by 4.
Divisibility Rule of 5
Numbers, which last with digits, 0 or 5 are always divisible by 5.
Example: 10, 10000, 10000005, 595, 396524850, etc.

1) 5437 × 1001
=5437 × (1000+1)
= 5437× 1000 + 5437× 1
=5437000 + 5437
=5442437
2)
824× 25
= 824 × (20+5)
= 824× 20 + 824 × 5
=16480+4120

Medicines are packed in boxes. One box weighs 4kg 500g.
We need to find many the number of boxes that can be loaded in a can that cannot carry beyond 800kg.
Solution:
The weight of one box = 4 kg 500 g = 4 × 1000 g + 500 g = 4500 g { As we know that 1kg = 1000g}
Maximum load can be loaded in can = 800 kg = 800 × 1000 g = 800000 g
Hence total weight=Maximum load can be loaded in can =800000 g
Number of boxes = Total weight / Weight of each box
Number of boxes = 800000/4500 = 177
Number of boxes = 177
Therefore, 177 boxes can be loaded in a can that cannot carry beyond 800kg.

1) 12,904 +2,888
Rounding off 12,904 to the nearest thousands we get, 13,000
And rounding off 2,888 to the nearest thousands we get, 3000
Therefore, 13,000 + 3,000 = 16, 000
Therefore, estimate of 12, 904 + 2,888 is equal to 16,000 according to the general rule.
2)28,292 – 21,496
Rounding off 28,292 to the nearest thousands we get, 28,000
And rounding off 21,496 to the nearest thousands we get, 21,000
Therefore, 28,000 - 21,000 = 7,000
Therefore, estimate of 28,292 - 21,496 is equal to 7,000 according to the general rule.
3)9250 × 29
Rounding off 9250 to the nearest thousands, we get 9000
And, rounding off 29 to the nearest tens, we get 30
Therefore, 9000 x 30 = 2,70,000
It means that estimate of 9250 × 29 is equal to 2,70,000 using general rule.

We know that 1 day is equal to 24 hours
1 hour = 1/24 day
So 8 hours = (1/24) × 8
8 hours = 8/24 day
8 hours = 1/3 day
Hence 1/3 of a day is 8 hours.
