Question

In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving AC > EF given BC = EF . Upload the entire proof below.
Given:

BC = EF


Prove:

AC > EF

Answer 1

A two column proofs is used to prove a conjecture using a table of two columns

The two column proof is:

• (a) $BC = EF$ ---------- Given
• (b) $AC = AB + BC$ ---- Betweenness
• (c) $AC = AB + EF$ --- substitution property of equality
• (d) $AC > EF$ ---- proved

Given that:

$BC = EF$

To prove that $AC > EF$, we make use of the following steps

Start by stating the given parameter

(a) $BC = EF$ ---------- Given

Because point B is in between collinear points A and C, then we have:

(b) $AC = AB + BC$ ---- Betweenness

Substitute EF for BC. So, we have:

(c) $AC = AB + EF$ --- substitution property of equality

The above means that:

(d) $AC > EF$ ---- proved
