Verbal reasoning — Odd one out: Select the term that does NOT belong with the others (angle types vs. line relationships).

Difficulty: Easy

acute
right
obtuse
parallel

Correct Answer: parallel

Explanation:

Introduction / Context:
Basic geometry vocabulary separates angle classifications from relationships between lines. Three choices name angle types; one describes how two lines can relate. Recognizing that categorical boundary is the target skill.

Given Data / Assumptions:

Options: acute, right, obtuse, parallel
Standard Euclidean definitions apply.

Concept / Approach:
Sort by concept: angle measure vs. line relation. Acute, right, and obtuse all label angle magnitude categories. “Parallel” is a relation between two lines that never meet. It is not an angle type and therefore is the outlier.

Step-by-Step Solution:

acute → angle less than 90 degrees.right → angle exactly 90 degrees.obtuse → angle greater than 90 and less than 180 degrees.parallel → lines with equal direction vectors, never intersecting; not an angle.

Verification / Alternative check:

Ask if each term can precede the word “angle” meaningfully. “Acute/right/obtuse angle” are valid; “parallel angle” is not standard usage.

Why Other Options Are Wrong:

acute / right / obtuse: Proper angle categories; thus they belong together.

Common Pitfalls:

Associating parallel lines with 0 degrees or 180 degrees and confusing that with an angle classification; the term itself does not name an angle.

Verbal reasoning — Odd one out: Select the term that does NOT belong with the others (angle types vs. line relationships).
