Imposible triangle
1 answer
The triangle with side lengths 8cm, 1cm, and 8cm is an impossible triangle because the sum of the lengths of any two sides of a triangle should be greater than the length of the third side. In this case, the sum of the lengths of the two shorter sides (1cm + 8cm) is equal to the length of the longest side (8cm), which violates this rule.
