Design and implement the following class

Class name: Triangle

Instance variables: triangle$\_$name, side$1,$ side$2,$ side$3$

Instance methods:

constructor: it initializes all the instance variables

calc$\_$perimeter: this method returns the perimeter of the triangle, calculated using: perimeter $=$ side $1+$ side $2+$ side$3$

calc$\_$area: this method returns the area of the triangle using:

where area $=\sqrt[\phantom{2}]{s(s-\text{s}\text{i}\text{d}\text{e}1)(s-\text{s}\text{i}\text{d}\text{e}2)(s-\text{s}\text{i}\text{d}\text{e}3)}$

$q,s=\frac{\text{s}\text{i}\text{d}\text{e}1+\text{s}\text{i}\text{d}\text{e}2+\text{s}\text{i}\text{d}\text{e}3}{2}ge{t}_n$ame: this method returns the name $of$ the triangle

where

Then write a Python program that reades the content of the text file "triangle.txt$"$ and create a list of Traingle objects. Each object should be constructed from each line of the text file. The program should print the following:

A table of all triangles along with their sizes and perimeters

The triangle name that has the smallest size
