Question

select the term that best describes the statement. all lines are straight or a triangle has four sides. conditional negation disjunction conjunction

Explanation:

• A conditional statement has the form "if p, then q". This statement doesn't have that form.
• A negation is the opposite of a statement, usually using "not". This statement isn't a negation.
• A disjunction is a compound statement formed by connecting two statements with "or". The given statement connects "All lines are straight" and "a triangle has four sides" with "or", so it's a disjunction.
• A conjunction is a compound statement formed by connecting two statements with "and". This statement uses "or", not "and".

Answer:

C. disjunction
