OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Transcribed Image Text:Implement a class Triangle. A Triangle is defined by the x- and y- coordinates of its three corner
points.
Your job is to compute the following properties of a given triangle:
the lengths of all sides (methods getSidelLength, getSide2Length, getSide3Length)
• the angles at all corners (methods getAnglel, getAngle2, getAngle3)
• the perimeter (the getPerimeter method)
• the area (the getArea method)
Implement a Triangle class using the template provided here: Triangle.java
Example:
Triangle triangle = new Triangle (0, 5, 1.5, 2, 8, 25.92);
triangle.getSidelLength(); // 3.3541019662496847
triangle.getSide2Length (); // 22.39746414217467
triangle.getSide3Length (); // 24.787424230847385
triangle.getAnglel (); // 2.312694531902217
triangle.getAngle2 (); // 0.7289796952097912
triangle.getAngle3 (); // 0.09991842647778622
triangle.getPerimeter(); // 50.53899033927174
triangle.getArea (); // 27.690000000000044
