Is pqr similar xyz if so name which similar postulate or Therom applies?

Triangles PQR and XYZ are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional. This can be established using the Angle-Angle (AA) Similarity Postulate, which states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar. If you can confirm the equality of the angles or the proportionality of the sides, then PQR is similar to XYZ.
