Assume that isIsosceles is a boolean variable, and that the variables isoCount, triangleCount, and polygonCount have all been declared and initialized. Write a statement that adds 1 to each of these count variables (isoCount, triangleCount, and polygonCount) if isIsosceles is true.

if (isIsosceles){

           isoCount +=1;

           triangleCount +=1;

           polygonCount+=1;

       }

Explanation:

Using Java programming language, we have shown the full implementation.

The three variables  (isoCount, triangleCount, and polygonCount) were declared and initialized to 1,2,3 respectively

After the if condition, the new values for these variables are printed to the screen and they become 2,3,4 respectively. complete code is given below

public class num3 {

   public static void main(String[] args) {

       boolean isIsosceles = true;

       int isoCount = 1;

       int triangleCount=2;

       int polygonCount=3;

       if (isIsosceles){

           isoCount +=1;

           triangleCount +=1;

           polygonCount+=1;

       }

       System.out.println(isoCount);

       System.out.println(triangleCount);

       System.out.println(polygonCount);

           }

}

what is your question exactly? when you let me know i will gladly you. : )

solution:

the auto-correct option of the auto-correct tool enables you to add and delete words that do not follow abbreviation rules because:

it is a feature that allows outlook to correct common spelling and typing errors and to replace characters with symbols. we can also can use auto-correct as a shortcut, which means we can type a small string of characters and have those characters replaced by a longer string.
