write a two column proof to prove the following. If AB=PQ and PQ=RS, then AB=RS.

Question

I need statements and reasons and properties

Answer 1

1. AB=PQ	AB and PQ are the same length which we can call x units.
2. PQ=RS	PQ and RS are the same length, so RS has length x units.
3. AB=RS QED	Since RS is x units long and AB is also x units long, AB is the same length as RS.

 

Comments

The properties are all length.
