Question

this is a question from computer java can anyone help me to answer this question ​

Answer 1

Explanation:

Algorithm. Step 1: Declare three sides of triangle. Step 2: Enter three sides at run time. Step 3: If side1 == side2 && side2 == side3 Go to step 6 Step 4: If side1 == side2 || side2 == side3 || side3 == side1 Go to Step 7 Step 5: Else Go to step 8 Step 6: Print the triangle is equilateral.

Answer 2

Type of Triangle - Java

In Geometry, a triangle is a three-sided polygon with three edges and three vertices. A triangle with vertices A, B, and C denoted ΔABC.

A triangle is said to be an EQUILATERAL TRIANGLE if all the sides are equal in measure.

A triangle is said to be an ISOSCELES TRIANGLE if any two sides are equal in measure.

A triangle is said to be a SCALENE TRIANGLE if none of the sides are equal in measure.

Let's implement the same logic in the program to check the type of triangle.

Here's our program:

$\rule{300}{2}$

import java.util.Scanner;       // Creating scanner class

public class Type_of_Traingle       // Creating class

{

   // The MAIN function

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

    // Taking user input to accept the length of the first side of a triangle and storing it in double data type

 System.out.print("Enter the length of the first side of a triangle: ");

 double a = sc.nextDouble();

 // Taking user input to accept the length of the first side of a triangle and storing it in double data type

 System.out.print("Enter the length of the second side of a triangle: ");

 double b = sc.nextDouble();

 // Taking user input to accept the length of the first side of a triangle and storing it in double data type

 System.out.print("Enter the length of the third side of a triangle: ");

 double c = sc.nextDouble();

 // Closing scanner class after the use

 sc.close();

 // If all sides of a trinagle are equal, it is a equilateral triangle

 if (a == b && b == c) {

     System.out.println("EQUILATERAL TRAINGLE.");

 }

 // If two sides of a trinagle are equal, it is a isosceles triangle

 else if (a == b || b == c || a == c) {

     System.out.println("ISOSCELES TRAINGLE.");

 }

 // If non of the sides of a triangle are equal, it is a scalene triangle

 else if (a != b && b != c && a != c) {

     System.out.println("SCALENE TRAINGLE.");

 }

 // If the inputs are invalid

 else {

     System.out.println("Invalid Input");

 }

}

}
