Explanation:

Step1: Analyze Problem Type

The problem involves triangle congruence (e.g., SAS, HL) and visual checks of triangle diagrams. This falls under Geometry (Mathematics subfield).

Step2: Identify Task (Example for Q25)

For question 25, we check triangle congruence via HL (Hypotenuse-Leg for right triangles). Both triangles are right-angled, have one leg equal (marked), and hypotenuse equal (marked). So HL applies.

(Repeat similar steps for other questions, checking congruence criteria against marked sides/angles.)

Answer:

(For each question, e.g., Q25: Congruent by HL; Q28: Not congruent (sides/angles don't match HL/SAS/ASA); etc. Specific answers depend on each diagram's markings. For example, Q25: The two right triangles are congruent by HL. )

(Note: Since the user provided a set of triangle congruence problems, the answer would involve verifying each using congruence criteria. For a specific question, e.g., Q25, the answer is that the triangles are congruent by HL. If a question like "Is Q28 congruent?" the answer is No, as the marked sides/angles don't satisfy a congruence criterion.)
