Question

can a triangle be formed with the side lengths of 8 cm 4 cm and 12cm

Answer 1

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

Answer 2

no because the sum of the measures shorter lengths. hope this helped
