Which pairs of quadrilaterals can be shown to be congruent using
Zielflug [23.3K]

Rigid transformation do not alter the sides and angle measurements of a shape.

The true statements are:

  • <em>quadrilateral 1 and  quadrilateral 2 - Not congruent </em>
  • <em>quadrilateral 1 and  quadrilateral 3 - Not congruent </em>
  • <em>quadrilateral 1 and  quadrilateral 4 - Not congruent </em>
  • <em>quadrilateral 2 and  quadrilateral 3 - Congruent </em>

<em />

From the graph, we have the following highlights

  • Quadrilaterals 2, 3 and 4 are congruent
  • Quadrilateral 1 does not have equal measure with any of the other quadrilaterals.

Hence, the first three statements are not congruent, while the last statement is congruent.
