Answer:
1. B
2. C
Explanation:
1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE
2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.
