Problem $1.$ Write a class named point in python which has data on cartesian coordinates $($x$,$y$)$ and has methods $(1)$ to convert convert cartesian coordinates to polar coordinates, $(2)$ to print cartesian coordinate $(3)$ to print polar coordinate of the point $(4)$ to compare two points and has a boolean output $(5)$ to find the distance between two points. Instantiate an object of the point class with assigned data.Problem $2.$ Write a derived class triangle which is made of$($bounded by$)$ three lines, and each line is represented by two points $($start and end$).$ Write methods in the hierarchy and use code blocks for the tow methods of triangle $(1)$ findAread and $(2)$ findPerimeter. Write the code in python.Problem $3.$ Write a multithreading code in python which has $15$ airlinesAgent as threads each selling $10$ tickets of total $150$ tickets. The sellTicket function should have prompts as each ticket sold by an agent$($use an agent id$)$ and notifying when the quota of selling tickets by each agent is done. Use lock in critical section to output the selling tickets by threads in a sequential manner.
