Proof: Midpoint Distance 2b

Let's prove the following theorem:

Proof:

Proof Table

#	Claim	Reason
1	(distance MB) ⋅ 2 = distance AB	if M is the midpoint of line AB, then (distance MB) ⋅ 2 = distance AB (Midpoint Distance 2)
2	distance AB = (distance MB) ⋅ 2	if (distance MB) ⋅ 2 = distance AB, then distance AB = (distance MB) ⋅ 2 (Symmetric Property of Equality)
