No, a triangle cannot be formed with side lengths of 8 cm, 4 cm, and 12 cm. This is because of the triangle inequality which states that the sum of any two of the side lengths of a triangle must be greater than the length of the third side.

This means that 8 + 4 must be greater than 12, however, it is not, it is equal to 12.

Therefore, no a triangle can NOT be formed with the side lengths of 8 cm, 4 cm, and 12 cm.

no, because the sum of the measures shorter legnths of the sides must be greater than the measure of the greatest angle

4+8=12
so therefor the side legnths if you tried to make into a triangle, it would make a line 12 units long

no is the answer
