Answer:
3
isosceles
greater
3
Explanation:
An isosceles triangle is a triangle that has two sides of equal length, so the lengths could be either 1, 1, 3 or 1, 3, 3. Since 1, 1, 3 is less likely, 1, 3, 3 is more likely to be the isosceles triangle.
The length of the third side is (3) in. The third side must be congruent to one of the other two sides because the triangle is (isosceles). The third side cannot measure 1 in. Because 1 + 1 is not (greater) than 3. So the third side must be measure (3) inch.
