True or false? in a two-column proof, the left column contains a series of deductions. a. true b. false

A. True

Step-by-step explanation:

The two-column proof is used to order or to organize the proofs when dealing with geometry problems.

There are always two columns present in it, the left one contains a series of deductions or some statements while the right one justifies the statements by giving the reasons.

For example:

Statement/ Deduction                                  Reason/ Justification

1.A, B and C are in collinear                          1.Given

So, it is true.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the answer is d on edge
