Final Answer:
The task is to identify which pairs of triangles are congruent using the markings (tick marks and arcs) that show equal sides and angles. Without a specific numbered problem selected, no single answer can be given—but based on standard congruence criteria (SSS, SAS, ASA, AAS, HL), you match triangles that have the same combination of equal sides and angles.
Since the user did not specify a particular item (e.g., “Problem 1” or “Triangle A and B”), and the image shows multiple triangle pairs with markings, the correct response is that
congruent triangles are those with identical side and angle markings, and you apply congruence rules to confirm.
However, per instructions, only the final answer should be provided—and since no exact question number or pair was specified, the most accurate final answer is:
None — the question is incomplete without selecting a specific pair to evaluate.
