Two triangles are shown to be congruent by identifying a combination of translations, rotations, or reflections that move one figure onto the other. If ΔACB ≅ ΔPRQ, which angle must be congruent to ∠C? Why? A)∠Q because corresponding parts of congruent triangles are congruent.
B)∠R because corresponding parts of congruent triangles are congruent.
C)∠Q because the triangles are isosceles and the base angles are congruent.
D)∠R because the triangles are isosceles and the base angles are congruent.
