Answer:
if( isIsosceles==true)
{
isoCount=isoCount+1;
triangleCount=triangleCount+1;
polygonCount=polygonCount+1;
}
Explanation:
According to question isIsosceles is a boolean variable so we check the condition of isIsosceles variable . if(isIsosceles==true) then it will executed the statement inside the if block that means it will increase the variable isoCount,triangleCount, and polygonCount by 1
i.e isoCount=isoCount+1;,
triangleCount=triangleCount+1;
polygonCount=polygonCount+1;
