请用中国初中的数学知识详细解答上面的数学问题。---**Question Number and Points:** 25. (6 分) **Question Stem:** 如图, 在三角形 ABC 中, AB=AC, 点 B、P、Q 三点在同一条直线上, 且∠ABP=∠ACQ, ∠BAC=∠PAQ=62°. 求∠APQ 的度数. **Chart/Diagram Description:** * **Type:** Geometric figure illustrating a triangle and points on a line. * **Main Elements:** * **Shapes:** Triangle ABC. * **Points:** Vertices A, B, C. Points P and Q are shown on the straight line passing through B and C. P is located inside the triangle, approximately on the segment BC. Q is located outside the triangle, extending from C. The points B, P, and Q are collinear. * **Lines/Segments:** Segments AB, AC, BC, AP, AQ, BP, PQ are drawn. The line passing through B, P, Q is shown as a straight line. * **Labels:** Points are labeled A, B, C, P, Q. * **Relative Position:** A is positioned above the line BQ. B, P, Q are on a straight line, with P between B and Q (specifically, between B and C according to the visual and the context of P being inside triangle ABC, and Q extending beyond C). **Mathematical Information/Conditions:** * Triangle ABC. * AB = AC (Triangle ABC is isosceles). * Points B, P, Q are on the same straight line. * ∠ABP = ∠ACQ. * ∠BAC = 62°. * ∠PAQ = 62°. **Question Asked:** Find the measure of ∠APQ.
