Question

the graph shows triangles cde and vwx. is cde congruent to vwx? justify your answer. yes, because a rotation 180° around the origin maps cde onto vwx. yes, because a reflection across the y - axis maps cde onto vwx. no, because \\( \overline { d e } \\) and \\( \overline { w x } \\) do not have the same length. no, because \\( \overline { c d } \\) and \\( \overline { v w } \\) do not have the same length.

Explanation:

Step1: Calculate the length of \( \overline{CD} \)

Use the distance formula \( d=\sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2} \). For points \( C(8,2) \) and \( D(3,3) \), \( x_1 = 3,y_1 = 3,x_2 = 8,y_2 = 2 \).

$$ LATEXBLOCK0 $$

Step2: Calculate the length of \( \overline{VW} \)

For points \( V(-8,-2) \) and \( W(-4,-3) \), \( x_1=-8,y_1 = -2,x_2=-4,y_2=-3 \).

$$ LATEXBLOCK1 $$

Since \( CD=\sqrt{26}\) and \( VW=\sqrt{17}\), \( CD
eq VW \). Congruent triangles have all corresponding sides equal.

Answer:

No, because \( \overline{CD} \) and \( \overline{VW} \) do not have the same length.
