Geometry

Question Analysis:
This question involves deductive reasoning about the properties of right angles.
The main focus is on applying a general rule to a specific case.

Key Concept Explanation:
Deductive reasoning starts with a general statement (all right angles are congruent) and applies it to a specific case (angle A is a right angle).

Step-by-Step Solution:
Start with the general rule: All right angles are congruent.
Apply the rule to angle A: Since angle A is a right angle, it must be congruent to all right angles.

Option Analysis:
A) Incorrect: Right angles are not acute.
B) Incorrect: Right angles are not obtuse.
C) Correct: This follows logical...
