Side BC is congruent to side BC.
Using the congruent angles and the angle bisectors, you can get two angles congruent to two other angles, so you use ASA to prove the triangles congruent. Then you use CPCTC to prove the sides congruent.
Answer: C.) ASA
The first one is the answer
Distance between two points, d, is given by

where: (x1, y1) = (8, 2) and (x2, y2) = (3, 8)
The first is an irrational number and the rest are rational
Any number that can be reduced or written as a fraction is a rational number
