No. With the given side lengths the sum of the two shorter sides do not exceed the length of the longest side and would not meet to form a triangle
no
that's an iscoceles triangle...
No
Isosceles.
No, a triangle cannot have side lengths of 1 cm, 2 cm, and 3 cm because they do not satisfy the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 1 cm + 2 cm is not greater than 3 cm, so a triangle cannot be formed with these lengths.

If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
Lenths of the 2 shortests sides added together has to be greater than length of the longest side.
No
Isosceles.
These dimensions do not form a triangle.
yes
A triangle with 2 equal side lengths is called an isosceles triangle.
An isoceles triangle has 2 congruent sides of equal length, and one of a different length.(If all three side lengths are the same, you have an equilateral triangle, which is also equiangular, each angle 60°).
isoceles triangle
No. 1/2 base squared + height squared=side squared on an equilateral triangle.
