Extracted 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
