Proof: Distance Property 1

Let's prove the following theorem:

if distance AB = x, then distance BA = x

Proof:

View as a tree | View dependent proofs | Try proving it

Given

1	distance AB = x

Proof Table

#	Claim	Reason
1	distance AB = distance BA	distance AB = distance BA (Distance Equality Property)
2	distance BA = x	if distance AB = distance BA and distance AB = x, then distance BA = x (Transitive Property of Equality Variation 2)
