Question

proofs with parallel lines and transversals
geometry - proofs with parallel lines and transversals
given: lines b and c are parallel
and line a is a transversal.
prove: ∠1 is supplementary to ∠7.

1. most of the time, when you

write a 2 column proof, you
start by what is given.
true
false

Explanation:

In a 2 - column proof, the standard approach is to start with the given information. This provides the foundation for the subsequent logical steps in the proof. Since the problem states "Most of the time, when you write a 2 column proof, you start by what is given", and starting with the given is a fundamental and common practice in constructing 2 - column proofs.

Answer:

True
