Question

1. lee begins to build a model of a barn by arranging the framing sticks into three groups of congruent lengths. how should these sticks be grouped?

Explanation:

Step1: Recall the concept of congruent lengths.

Congruent lengths mean equal - length segments.

Step2: Group segments by visual inspection of length.

By looking at the lengths of the line - segments, we can group them. Assume we measure or visually estimate the lengths. Let's say segments \(AB\) and \(CD\) have the same length, segments \(EF\) and \(KL\) have the same length, and segments \(IJ\), \(GH\), and \(RS\) have the same length.

Answer:

Group 1: \(AB\), \(CD\); Group 2: \(EF\), \(KL\); Group 3: \(IJ\), \(GH\), \(RS\)
