Final answer:
Triangles can be determined to be similar using various methods based on congruent angles and proportional sides.
Step-by-step explanation:
Triangles are similar if their corresponding angles are congruent and their corresponding sides are proportional. There are several methods to determine if triangles are similar:
A. AA (Angle-Angle):
If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
B. SSS (Side-Side-Side):
If the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.
C. SAS (Side-Angle-Side):
If two sides of one triangle are proportional to two sides of another triangle and the included angles are congruent, then the triangles are similar.
Based on the information provided in your question, it is not specified which method is applicable. Therefore, the answer would be D. Not similar. Without additional information, we cannot determine if the triangles are similar using any of the given methods.
