Question

if fg = 2 units, fi = 7 units, and hi = 1 unit, what is gh?
3 units
4 units
5 units
6 units

Explanation:

Step1: Use segment addition postulate

From the segment addition postulate, we know that \( FI=FG + GH+HI \).

Step2: Solve for \( GH \)

Rearrange the formula to \( GH=FI - FG - HI \).
Substitute \( FI = 7\), \(FG = 2\), and \(HI = 1\) into the formula: \( GH=7 - 2 - 1\).
Calculate \(7-2 - 1=4\).

Answer:

4 units
