John given task to his friend in order to check whether a triangle is valid or not if angles are given using if else.
**Property of a triangle : **
С.
a
b Б
a+b+c= 180°
Note: A triangle is said to be a valid triangle if and only if sum of angles is 180 deg.
Input Format

Program :
import java.util.*;
class Triangle {
public static void main(String args[])
{
Scanner Sc = new Scanner(System.in);
int angle1 , angle2 , angle3;
System.out.print("Enter Angle 1 : ");
angle1 = Sc.nextInt();
System.out.print("Enter Angle 2 : ");
angle2 = Sc.nextInt();
System.out.print("Enter Angle 3 : ");
angle3 = Sc.nextInt();
if(angle1 + angle2 + angle3 == 180)
{
System.out.print("Triangle is valid. \nBecause the sum of angles is : " + (angle1 + angle2 + angle3));
}
else
{
System.out.print("Triangle is not valid. \nBecause the sum of angles is " + (angle1 + angle2 + angle3) + " which is not equal to 180");
}
}
}
Output 1 :
Enter Angle 1 : 20
Enter Angle 2 : 20
Enter Angle 3 : 20
Triangle is not valid.
Because the sum of angles is 60 which is not equal to 180
Output 2 :
Enter Angle 1 : 60
Enter Angle 2 : 90
Enter Angle 3 : 30
Triangle is valid.
Because the sum of angles is : 180
