Chapter 10.5, Problem 1WE

To determine

To calculate:Divide $\overline{AB}$

into three congruent segments.

Answer to Problem 1WE

  

Explanation of Solution

Given information: $\overline{AB}$ is roughly $15$ cm long.

Calculation:

  

Step 1: let’s first draw a line at any angle with a given line as shown in figure

Step 2: Mark three equal parts with compass in this new line

Step 3: Now, joint point 3 and B

Step 4: Make an arc from point 3 to line 3B, and copy that arc from point 2 and point 1

Step 5: Join these intersections and point 1 and 2 to make parallel lines with 3B. Intersection of these lines with AB are X and Y, which divide line AB into exactly three parts.
