Geometry

Question Analysis:
This question involves applying syllogistic reasoning to geometric properties of triangles.
The main focus is on deducing a valid conclusion from the given premises.

Key Concept Explanation:
A syllogism connects two premises to form a conclusion. Here, the premises relate right triangles and their properties.

Step-by-Step Solution:
Premise 1 states that all right triangles have one 90-degree angle.
Premise 2 states that Triangle XYZ is a right triangle.
Combining these, we conclude that Triangle XYZ has one 90-degree angle.

Option Analysis:
A) Correct: Follows logically from the premises.
B) Incorrect: Contradicts the premises....
