Java Program to find Angle of a Triangle

Write a Java Program to find the Angle of a Triangle with an example. This Java example allows entering the remaining two angles of a triangle. As we all know, the sum of three angles in a triangle equals 180. So, subtracting the given two angles from 180 gives the third angle of a triangle.

package Area;

import java.util.Scanner;

public class AngleOfTriangle1 {
	private static Scanner sc;

	public static void main(String[] args) {
		int ang1, ang2, ang3; 
		sc = new Scanner(System.in);
		
		System.out.println("Enter two angles of a Triangle =  ");
		ang1 = sc.nextInt();
		ang2 = sc.nextInt();
		
		ang3 = 180 - (ang1 + ang2);

		System.out.format("The Third Angle of a Triangle = %d",ang3);
	}
}
Enter two angles of a Triangle =  
60
45
The Third Angle of a Triangle = 75

In this Java program, we declared a TriangleAngle function that returns a triangle’s remaining or third angle.

package Area;

import java.util.Scanner;

public class AngleOfTriangle2 {
	private static Scanner sc;

	public static void main(String[] args) {
		int ang1, ang2, ang3; 
		sc = new Scanner(System.in);
		
		System.out.println("Enter two angles of a Triangle =  ");
		ang1 = sc.nextInt();
		ang2 = sc.nextInt();
		
		ang3 = TriangleAngle(ang1, ang2);

		System.out.format("The Third Angle of a Triangle = %d",ang3);
	}
	
	public static int TriangleAngle(int ang1, int ang2) {
		return 180 - (ang1 + ang2);
	}
}
