Question

3cm 4cm and 7cm are not the length of a triangle explain why

Answer 1

To form a triangle the sum of length of two small sides must be greater than the greater side.

But here 4+3 = 7

Which is not greater than third side hence they are not length of a triangle.

Hope it helps.

Answer 2

Answer:

It does not form a triangle because triangle has a rule that if we add 2 measurements (that are smaller) they should be greater than the third one

That is, 3+4 should be greater than 7
