Sure! It will be an isosceles triangle.
No
No. It is not possible. * * * * * Yes, it is.
Yes.
yes
If you mean side lengths of 5, 4 and 1 then it is not possible to construct any triangle from the given dimensions.
Yes and it will be in the form of an isosceles triangle having two equal sides.
Not always, but it is possible. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.
No, to form a triangle, the two smaller lengths must add up to be more than the other length.
No because the sum of the smaller lengths must be greater than the longest length
No. Each side must be shorter than the sum of the other two sides.
No 1+3=4, which is less than 5
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.
