Ioana tried to prove that \triangle OPQ\cong \triangle SRQ△OPQ≅△SRQtriangle, O, P, Q, \cong, triangle, S, R, Q. Statement Reason 1 PQ=RQ=9PQ=RQ=9P, Q, equals, R, Q, equals, 9 Given 2 m\angle O=m\angle S=90\degreem∠O=m∠S=90°m, angle, O, equals, m, angle, S, equals, 90, degree Given 3 m\angle PQO=m\angle RQS=63\degreem∠PQO=m∠RQS=63°m, angle, P, Q, O, equals, m, angle, R, Q, S, equals, 63, degree Given 4 \triangle OPQ\cong \triangle SRQ△OPQ≅△SRQtriangle, O, P, Q, \cong, triangle, S, R, Q Angle-side-angle congruence What is the first error Ioana made in her proof? Choose 1 Choose 1 (Choice A) A Ioana used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Ioana only established some of the necessary conditions for a congruence criterion. (Choice C) C Ioana established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Ioana used a criterion that does not guarantee congruence.
