Answer :

The Solution:

Given:

[tex]\begin{gathered} X=-7 \\ Y=-3 \\ Z=1 \\ W=5 \end{gathered}[/tex]

Required:

Determine whether segment XY is congruent to segment ZW.

Step 1:

Find the length of segment XY.

[tex]XY=-3-(-7)=-3+7=4[/tex]

Step 2:

Find the length of segment ZW.

[tex]ZW=5-1=4[/tex]

Since:

[tex]\begin{gathered} XY=ZW=4 \\ It\text{ follows that XTY and ZW are congruent.} \end{gathered}[/tex]

Answer:

XY = 4

ZW = 4

They are congruent.
