It assumes the statement is false

It uses known properties to conclude

They determine if a box can be pushed over

They are irrelevant to the proof

They illustrate the relationships necessary for induction

They show the weight of each box

That each element is independent

That the statement is false

That all elements are identical

That the first element can be pushed over

Checking every possible case

Showing that pushing one element affects the others

Proving the first element can be pushed over

Assuming the statement is false
