•  $\overline{CD}\ \cong\overline{DE}$  

•  $\overline{DE}\ \cong\ \overline{EF}$  
  

•  $\overline{EF}\ \cong\ \overline{FG}$  

•  $\overline{CE}\cong\overline{DE}$  

Finding the length of a segment:

•  $\left|a-b\ \right|\$  

Finding the length of a segment:

•  $\left|-4-17\ \right|\$  

•  $\left|-21\right|$  

• 21

•  $\overline{AB}\ =21$  

Example:

•  $\overline{AB}\ =14$  

•  $\overline{BC}=15$  

•  $\overline{AC}=14+15=29$
