Sometimes the difference in lengths between two line segments is not obvious. So, we are not always sure about our usual judgement.

No. Number 12 is divisible by both 6 and 4 but 12 is not divisible by 24.

4.Try to construct triangles using match sticks. Some are shown here.

Can you make a triangle with:
(a)3 matchsticks?
(b)4 matchsticks?
(c)5 matchsticks?
(d)6 matchsticks?
(Remember you have to use all the available matchsticks in each case)
If you cannot make a triangle, think of reasons for it.
Answer:
(a) 3 matchsticks
This is an acute angle triangle and it is possible with 3 matchsticks to make a triangle because sum of two sides is greater than third side.

(b) 4 matchsticks
This is a square, hence with four matchsticks we cannot make triangle.

(c) 5 matchsticks
This is an acute angle triangle and it is possible to make triangle with five matchsticks, in this case sum of two sides is greater than third side.

(d) 6 matchsticks
This is an acute angle triangle and it is possible to make a triangle with the help of 6 matchsticks because sum of two sides is greater than third side.

a × (b + c) = a × b + a × c
Distributive property of multiplication explains the distributing ability of an operation over another mathematical operation within a bracket. It can be either distributive property of multiplication over addition or distributive property of multiplication over subtraction.
Let’s consider the following example.
(–2) × (3 + 5) = –2 × 8 = –16 and;
[(–2) × 3] + [(–2) × 5] = (– 6) + (–10) = –16
So, (–2) × (3 + 5) = [(–2) × 3] + [(–2) × 5]
In general, for any integers a, b and c, a × (b + c) = a × b + a × c

Set of numbers which do not have any other common factor other than 1 are called co-prime or relatively prime numbers. This means those numbers whose HCF is 1.
For example, 8 and 9 have no other common factor other than 1 so they are co-prime numbers.

In equilateral triangle all angle of triangle are equal. so

Let each angle is x.
Now, we know that sum of all angles of triangle is 180o
So, x + x + x = 180
3x = 180
{tex}x = \frac{{180}}{3} = 60^\circ {/tex}
So, each angle is equal to 60o.
