Hey, @acoustic cave!
Please remember to /close this post once your question has been answered!

I have a Point Class as well

public class Point {
    private double x, y;
    private static final double DEFAULT_COORDINATE=0;

    public Point() {
        setX(DEFAULT_COORDINATE);
        setY(DEFAULT_COORDINATE);
    }
    public Point(double newX, double newY) {
        super();
        setX(newX);
        setY(newY);
    }
    public Point(Point newP) {
        setX(newP.getX());
        setY(newP.getY());
        
    }    
    
    public Point(int angleDegrees, double radius) {
        setX(radius*Math.cos(Math.toRadians(angleDegrees)));
        setY(radius*Math.sin(Math.toRadians(angleDegrees)));
    }
    
    public double getX() { return x; }
    public double getY() { return y; }
    
    public void setX(double newX) { this.x=newX; }  // note no validation is needed
    public void setY(double newY) { this.y=newY; }

    public void reflectXY() {
        double temp=x;
        setX(y);
        setY(temp);
    }
    
    public double distanceToOrigin() { return Math.sqrt(x*x + y*y); }    
    
    public double distanceTo(Point otherPoint) {         // local scope parameter
        double otherX=otherPoint.getX();   // local scope variables
        double otherY=otherPoint.getY();
        return Math.sqrt(Math.pow(x-otherX,2) + Math.pow(y-otherY,2));   // x and y, class instance scope
    }

    public String toString() {
        return "("+x+", "+y+")"; 
        }    
}```

this is my triangleTest file:

public class TriangleTest {  
    public static void main(String[] args) {
        
        
        
        System.out.println("Test Case 1b - constructors, toString");
        Triangle t2 = new Triangle(new Point(0.,0.), new Point(3.,0.), new Point(0.,4.));
        System.out.println("EXPECTED RESULT:(0.0, 0.0) (3.0, 0.0) (0.0, 4.0)");
        System.out.println("YOUR RESULT    :"+t2.toString());
        System.out.println("PASSED="+t2.toString().equals("(0.0, 0.0) (3.0, 0.0) (0.0, 4.0)")+"\n");

        System.out.println("Test Case 1c - constructors, toString");
        Point x = new Point(-1., 0.);
        Point y = new Point(1., 0.);
        Point z = new Point(0., 2.);
        Triangle t3 = new Triangle(x,y,z);
        System.out.println("EXPECTED RESULT:(-1.0, 0.0) (1.0, 0.0) (0.0, 2.0)");
        System.out.println("YOUR RESULT    :"+t3.toString());
        System.out.println("PASSED="+t3.toString().equals("(-1.0, 0.0) (1.0, 0.0) (0.0, 2.0)")+"\n");
    
        System.out.println("Test Case 1e - constructors, toString");
        t3.setP1(x);
        System.out.println("EXPECTED RESULT:(-2.0, 0.0) (1.0, 0.0) (0.0, 2.0)");
        System.out.println("YOUR RESULT    :"+t3.toString());
        System.out.println("PASSED="+t3.toString().equals("(-2.0, 0.0) (1.0, 0.0) (0.0, 2.0)")+"\n");
        
        System.out.println("Test Case 3a - isRightTriangle");
        Triangle t3a = new Triangle();
        System.out.println("EXPECTED RESULT:false");
        System.out.println("YOUR RESULT    :"+t3a.isRightTriangle());
        System.out.println("PASSED="+(t3a.isRightTriangle()==false)+"\n");


        System.out.println("Test Case 3e - isRightTriangle");
        Triangle t3e = new Triangle( new Point(-5., 0.),new Point(0., 0.),new Point(0., -12.));
        System.out.println("EXPECTED RESULT:true");
        System.out.println("YOUR RESULT    :"+t3e.isRightTriangle());
        System.out.println("PASSED="+(t3e.isRightTriangle()==true)+"\n");
    }
}```

i need help figuring out my error in my triangle file because I cannot get the right print statement to go

as well as the isRightTriangle method is throwing the wrong values

I don't know where I went wrong that it is not displaying the right values or being passed the right values to get the right output
