We have seen how to get 90 degrees using paper folding . Now, suppose we do not have any paper but two sticks of equal length and a thread . How do we make an exact 90 degrees using these ?

Dear Student,
To make a perfect 90° angle using only two sticks and a thread. Follow the steps given below:
1- Take two sticks of equal length (AB and CD). Tie their ends with a thread, making a rhombus.
2- Fix one point A. Pull points B and D apart until the thread is fully stretched and the shape becomes a perfect square (diagonals are equal & bisect at 90°).
Now, place the thread along the diagonal AC or BD—it will be exactly perpendicular to the other diagonal.
The thread now marks a perfect right angle
All the best for your future
