Proof: Transitive Property Application 1
Let's prove the following theorem:
if the following are true:
    
    
    
    - a = b
- b = c
- c = d
then a = d
Proof:
  
      
      Given
      
    
    
      
  
  
| 1 | a = b | 
|---|---|
| 2 | b = c | 
| 3 | c = d | 
| # | Claim | Reason | 
|---|---|---|
| 1 | a = c | if b = c and a = b, then a = c | 
| 2 | a = d | if c = d and a = c, then a = d |
