4. In questions where you have to prove LHS=RHS, remember that you can make any change in the LHS only and you cannot modify RHS.

5. Make sure that all the given information is translated into a diagram. Try making it as accurate as possible. Knowing the quadrants or points makes it easier to find the final answer.

6. Instead of using a name such as ABC, write ABC as 1 and so on. It will save you a lot of time. Sometimes it creates confusion when you have multiple angles in the said question like ABC, ACB etc. Always remember to mark the points, i.e. 1, 2 in the diagram.

7. Important properties of some quadrilaterals:

Parallelogram - if opposite sides are equal, diagonals are unequal

Rectangle - if opposite sides are equal and the two diagonals are also equal

Rhombus - if all sides are equal but diagonals are unequal

Square - if all sides are equal and diagonals are also equal

8. Practice questions related to Midpoint formula, section formula, Area of a triangle.
