Proof: Midpoint Distance 2b
Let's prove the following theorem:
if M is the midpoint of line AB, then distance AB = (distance MB) ⋅ 2
Proof:
Given
| 1 | M is the midpoint of line AB |
|---|
| # | Claim | Reason |
|---|---|---|
| 1 | (distance MB) ⋅ 2 = distance AB | if M is the midpoint of line AB, then (distance MB) ⋅ 2 = distance AB |
| 2 | distance AB = (distance MB) ⋅ 2 | if (distance MB) ⋅ 2 = distance AB, then distance AB = (distance MB) ⋅ 2 |
