A student creates a triangle with a perimeter of 13 inches. According to the student, the longest side is 9 inches. Explain how you know the student is incorrect.
Can someone please help, i’ll mark brainliest!!
The student is wrong because the sum of any two sides of a triangle should be greter than the third side. The length of a single side of a triangle can not be half or more than half of the perimeter of that triangle. And since the given length is more than half of the perimeter , the student is incorrect .
