* Rotation is nothing but rotating an object through an angle of 90 degrees, 180 degrees, 270 degrees either clockwise or anticlockwise.

* For rotating 90 degrees clockwise and anticlockwise the steps are same

* For rotating 180 degrees clockwise and anticlockwise the steps are same

First, we will look into 90-degree rotation(it may be clockwise or anticlockwise)

for 90 degrees rotation, the co-ordinates (from the quadrant it is plotted) should be swapped and changed(signs) according to the destination it is going.

For example, consider a co-ordinate (2,3) from the co-ordinate we know that it lies in the first quadrant. In the question, if they are asking to rotate the given co-ordinate to 90 degrees clockwise and write the co-ordinate?

Solution: (2,3) lies in the first quadrant. In the first quadrant, both the x and y values are positive. Here we are going to rotate this co-ordinate to an angle 90 degree clockwise

The first step is we have to swap the points that are (3,2)

If the point is rotated to 90 degrees clockwise, it will go to the fourth quadrant. In the fourth quadrant, x values are positive, and y values are negative therefore the answer is (3,-2)

for 180 degrees rotation, the co-ordinates (from the quadrant it is plotted) should not be swapped; only the sign should be changed according to the destination quadrant.

Example 2: Rotate the point (-3,2) to 180 degrees clockwise

Solution: (-3,2) lies in the second quadrant. In the second quadrant, x values are negative, and y values are positive.

To rotate this co-ordinate 180 degree, the thing is we should not swap the points we should consider the numbers without a sign, i.e.(3,2)

If we rotate to 180 degrees clockwise, the points will go to the fourth quadrant. In the fourth quadrant, x values are positive, and values are negative; therefore, the answer is (3,-2).

In French, It is a common habit to greet a person whom you know or not. The complexity lies in the following factors:

- The person you greet (is it a person whom you are already well acquainted with or not)
- The age of the person (is the person younger or older)
- The gender of the person (are you dealing with a male or female)
- When dealing with a female (is she married or not)
- The time of the day (morning, noon, afternoon, evening, night, midnight)
- The circumstance (whether you are meeting the person or leaving the person)

When greeting in French, you first wish a good day, then politely ask about the well-being of the person we address ourselves to. Knowing already how to ask a question is not mandatory, but can help framing the question the right way.

A)
- Bonjour! Bonsoir! Salut! are used to say either Good morning, Good afternoon/evening or Hi/hello

Note: the object of the question would reply back by saying: Bonjour! Bonsoir! Salut

- Comment ca va?, Ca va?, Tu vas bien? Are used to say "How are you" to well known person and mostly a person of our age or younger.

Note: the object of the question would reply back by saying: Ca va bien (I a fine), Ca va mal (I am not fine), Comme ci comme ca (so so), Pas mal (I am ok, more good than bad)

B)
- Comment allez-vous? is used to say "How are you" to strangers, but also to know persons that are older to us.

Note: the object of the question would reply back by saying: Je vais bien, merci (I am fine thanks), Je vais mal (I am not fine).

C)
1- While meeting (saying for exp Good morning, after...):
- From 12 am to 12 pm use Bonjour
- From 12 pm to 12 am use Bonsoir

2- While leaving (saying have a good day/evening...):
- From 6 am to 12 pm use Bonne journey
- From 1 pm to 3 pm use Bonne apres-midi
- From 4 pm to 8 pm use Bonne soiree
- From 9 pm to 12 am use Bonne nuit

Note: It is not unlikely that a person would wish a good morning between 12 am to 6 am (while meeting as it is a new day that started) and Goodnight between 12 am to 2 am (while leaving as it is still dark)

2) polynomials: relations between roots and coefficients of equations ( quadratic and cubic both). How to write quadratic equations whose roots r given...
3) linear equations of two variables:
A condition of no solutions, infinity solutions, and unique solution,
Method to solve linear equations ( eliminating, cross, and substitutions)
4) coordinate geometry: section formula, the area of triangle formula and how to find ratio when coordinate is given
5) quadratic equations: completing square method, nature or roots,
6) Ap: nth term formula and summation formula
7) circle: theorem: ( tangent from an external point are equal)
8) Area related to circle: area of the sector and triangle area ( 1/2 r^2sin(Thota half angle)
9) construction: how to draw triangle when required is ( 3/4 type 5/3 type), how to draw a tangent from the external point.
10). Surface area and volume: all formula including frustum
11) : trigonometry: complimentary angle formula, and identity
12) application of trigonometry: tan60: root 3 and tan30: 1/root3
13) probability: formula
14) statistics: all formula for the mean( shortcut, assumed mean, and step deviations,), mode and median formula, and the relationship between them.. how to draw more than and less than ogive.

15) triangle: all theorem of this chapter (BPT, PYTHAGORAS theorem, and questions based on that, area of similar triangle related to side ) last exercise of NCERT last 7questions

These all topics are the important one ...

I hope this will be helpfull for you guys.
