Answer:

  A: the triangles are similar

  B: AB corresponds to QR

  C: ∠PAB corresponds to angle Q

Step-by-step explanation:

A line segment parallel to the base of a triangle will create a similar triangle. The AA similarity postulate can be used to conclude that.

__

Part A:

The triangles PQR and PAB are similar. This derives from the fact that angle P is in both triangles, and corresponding angles PAB and PQR are congruent. The AA congruence postulate applies.

__

Part B:

Based on the similarity statement, segment AB corresponds to segment QR.

__

Part C:

Transversal PQ crosses parallel lines AB and QR at points A and Q, respectively. The corresponding angles are PAB and PQR.
