Triangle ABC is congruent to TriangleA'BC' by the HL theorem.
Triangles A B C and A prime B C prime are connected at point B. Angles A prime C prime B and A C B are right angles. The lengths of C prime A prime and C A are congruent. The lengths of A prime B and B A are congruent.
What single rigid transformation maps TriangleABC onto TriangleA'BC'?
dilation
reflection
rotation
translation

Rotation.
Reason: Both triangles share B and are congruent with AB = A'B and CA = C'A'. The isometry must fix B and send A to A' while preserving distances, so a rotation about point B carrying ray BA to BA' will carry C to C' and map triangle ABC onto triangle A'BC'.
