To find ∡B, we can set up an equation using the fact that corresponding angles in congruent triangles are equal:
∡B = ∡P
To find ∡Q, we can set up another equation using the fact that corresponding angles in congruent triangles are equal:
∡Q = ∡C
So, to find ∡B and ∡Q, we just need to find the values of ∡P and ∡C.
However, the information given in the problem is not enough to determine the values of ∡P and ∡C. We need more information, such as the measures of ∡A, ∡B, ∡C, ∡P, ∡Q, and ∡R, or the lengths of the sides of △ABC and △PQR. Without additional information, we cannot determine the values of ∡B and ∡Q.
