Given that ΔPQR and ΔXYZ are congruent triangles, the measure of XY is: D) 4 units

Recall:

  • Congruent triangles have pairs of congruent angles and congruent sides.
  • Distance between two vertices can be calculated using the distance formula: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Given ΔPQR ≅ ΔXYZ, therefore, PQ = XY.

Find the distance between P(0, 0) and Q(-4, 0) using[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

[tex]PQ = \sqrt{(-4 - 0)^2 + (0 - 0)^2}\\\\\mathbf{PQ = 4 $ units}[/tex]

  • Since ΔPQR ≅ ΔXYZ, therefore the measure of XY is: D) 4 units
