Question

Write a program to input three angles of a triangle and check whether its construction is possible or not. (A triangle is possible if the sum of all the angles = 180). If possible then check and display whether it is an acute angled triangle, right-angled triangleor an obtuse angled triangle. Otherwise, display „A Triangleis not possible‟.Also write code to find the second largest angle.Sample
Input : Enter three angles : 30, 70, 80Sample Output : Right Angled triangle

Answer 1

Question:-

• WAP to input 3 angles of a triangle and check if construction is possible or not
• If yes, Check and display if a triangle is acute angled, right angled or obtuse angled triangle.
• Else Display " triangle not possible".
• Also find second largest angle

Code Language:-

• Not mentioned

Since the code language is not mentioned in the question, it is done in Java

Java Code:-

package Coder;

import java.util.*;

public class Triangle

{

public static void main (String ar [])

{

Scanner sc=new Scanner (System.in);

System.out.println("Enter 3 angles");

int a=sc.nextInt();

int b=sc.nextInt();

int c=sc.nextInt();

if((a+b+c)==180)

{

System.out.println("Triangle possible");

if(((a<90)&&(a>0)) ll (b<90)&& (b>0) ll(c<90)&&(c>0))

System.out.println("Acute angled Triangle");

else if((a==90)ll(b==90)ll(c==90))

System.out.println("Right angled triangle");

else if(((a>90)&&(a<180)) ll ((b>90)&&(b<180)) ll ((c>90)&&(c<180)))

System.out.println("Obtuse angled triangle");

}

else

System.out.println("Triangle not possible");

}

if(a>b)&&(b>c)

System.out.println(b+" is second largest angle");

else if(b>c)&&(c>a)

System.out.prinrln(c+" is second largest angle");

else

System.out.println(a+" is second largest angle");

}

}

Variable Description:-

1. a,b and c:- to accept 3 angles(each angle in onle variable) from the user
