Let's see a little bit about Angle?
What is Mathematics?
What would you say if asked that?
Yes, you say numbers.
That's how we started.
No matter how we start
and where we go around, we must start with numbers and end with numbers in
mathematical calculations.
There are only ten digits
in mathematics. We construct that 10 digits logically and convert it into
infinite numbers, don't we!
What are you doing now?
Are you sitting and
reading this?
How long will you be
studying? Get up a little and walk thirty feets, let's see.
What have you done? Do
you say yes? You have good speed and agility. So you've moved too quickly.
Today you are thinking
about what topic you are talking about without talking about Mathematics.
Don't you know that
even if we speak any topic, we will relate to it Mathematics?
Let's start the
Mathematics. How far have you gone yet?
You mean we went thirty
feet as you said?
How would you number
this? You are asking all this as a question, and you are a little angry saying
30 that we don't know if this is even.
Well, let it be. Let's
turn a bit from where we are standing now.
How far did you go?
Why are you having so
much fun today you ask?
There is the matter.
How far have you gone
now?
Are you angry with me
again, what are you playing?
Where did we go? You
said to turn slightly from where you were standing, you are saying that we
turned.
You are right. If I ask
why and how far you have gone, only then can you indicate this with a number.
You ask, how can this
be referred to in the length?
Your logic is also
correct. Mathematics is logic. You're turned. Not as it was before. A change
has occurred. Shouldn't that indicate how much change has taken place!
Shouldn't there be numbers to represent this too! Let's say your turn target is
approximately 30.
Earlier you walked. You
said 30 for how much.
Now you are turn. By
how much you mean 30.
But you know that the
30 steps you walk and the 30 you turned are not the same.
But if both are to be
represented by numbers, is it 30?
But you say it is
something not ok.
That's right. It is
correct to say distance covered as 30 in feet. How is it correct to say that the
turn is 30? But you turned 30?
But it's different, you
mean it's different?
You are right. Now you
are saying that these two 30 should be distinguished.
Yes, it must be
differentiated.
Let's say the 30 steps
you walked are 30. Let's distinguish only 30 turning from where you mark by
placing a dot or a small zero above 30.
That's how it is 300.
This is called 30 degree.
So if a number has a
dot or a small zero above it, it does not indicate a linear motion value, but a
rotational value, right?
Now we come to the topic
of angle. An angle is a turning or rotation.
An angle does not imply
linear motion. It represents circular motion. We need numbers to indicate that.
Can we create new numbers for that? We convert the existing numbers into angle
measures by placing a dot or a small zero above them.
What is the use of
these rotating angular scales you ask? Are there such rotating objects in this
world, you ask?
The angle itself
differentiates the shapes. Although a rectangle and a parallelogram have the
same area, how do they differ? Only in angular sizes. It is because of the
angle measure that its diagonals become different measures.
So is the square and
rhombus. How can a rhombus be made from a square if the angle measures between
the sides are right angles?
How do you tell that
the Tower of Pisa is leaning? At an angle.
Leave Pisa City Tower.
Our Earth itself rotates at an angle of 23½0. I don't think you will
ever ask where Angular is used anymore.
Do I even need to tell
you about objects that rotate in a particular place? The clock, the fan, the
windmill, the wheels of the vehicles all revolve as they are on the axis.
Mathematical knowledge of angle is very useful in all these.
Vow, can you finally
tell us about such an angle? Do you mean to teach first or not? You are right.
What if you study when?
Whatever you study in mathematics, in logic Since we have to learn and read it
in a logic, I decided to look at it at the end.
So let's look at the
next topic as angles.
