Answer:
b. SAS
Explanation:
These triangles can be proven congruent through SAS, or side, angle, side. SAS is used when two sides and one included angle are congruent. For an angle to be included, it must be in between the other two sides. This means the angle's rays are the congruent sides. If two lines have an equal number of tick marks, or if two angles have an equal number of arcs, then they are congruent. In this image, two line pairs are marked as congruent as well as the included angle. Therefore, the correct answer is B. SAS.
