No, they could only form a straight line.
No because the given dimensions would not form a triangle.
No they could not.
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
No because to form a triangle the sum of its two smaller sides must be greater than its longest side
Can 9, 8, and 17 for a triangle?
No, they could only form a straight line.
Yes, it would form a tall isosceles triangle. Add the smallest two (1+8=9 in this case). If it is greater than the longest (8 in this case) then they can form a triangle.
No, segments 1, 8, and 8 cannot form a triangle. In order for three segments to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 1 + 8 is equal to 9, which is not greater than 8. Therefore, a triangle cannot be formed.
17
An isosceles triangle
17 - (-9) - 8 = 17 + 9 - 8 = 18.
8 + 9 = 17
No. Because the total length of the two smaller sides (9 and 8) equal the length of the remaining side (17). No angles would be formed, so there would be no triangle. The total length of the two smallest sides has to be greater than the length of the longest side in order to make a triangle.
-8 - 17 = -25
17/9 = 1 and 8/9 + 8 = 9 and 8/9
-17
