Statements 1 and 3 are written in the "if-then" form. The hypothesis of Statement 1 is "If you work overtime." The conclusion is 'you'l be paid time-and-a-half." Statement 2 has the hypothesis after the conclusion. If the word if is in the middle of the statement, then the hypothesis is after it. The statement can be rewritten: If the weather is nice, then I will wash the car Statement 4 uses the word when" instead of if and is like Statement 2. It can be written: If l win the lottery, then I will be a millionaire. Statement 5 if and "then" are not there. It can be rewritten: Ifa triangle is equiangular, then it is equilateral. ​
