Prove Triangle congruence

What is the first error Ioana made in her proof?

a. Ioana used an invalid read to justify the congruence of a pair of sides or angles.

b. Ioana only established some of the necessary conditions for a congruence criterion.

c. Ioana established all necessary conditions, but then used an inappropriate congruence criterion.

d. Ioana used a criterion that does not guarantee congruence.

Answer :

Answer:

b

Step-by-step explanation:

To prove congruence by ASA postulate the included side must be the side between the congruent angles

1 PQ = RQ → given

2. ∠ PQO ≅ ∠ RQS → given

3 ∠ QPO ≅ ∠ QRS → sum of angles in a triangle

Then Δ OPQ ≅ Δ SRQ ( by the ASA postulate )

Her error was in not having the included side but only 2 angles
