Interactive multiple-choice quiz: Statements, Conditionals and Biconditionals - Reveal
Conditional statements form the foundation of logical reasoning and geometry. A conditional statement consists of a hypothesis (the 'if' part) and a conclusion (the 'then' part). From a given conditional statement 'If p, then q', various related statements can be formed: the converse (If q, then p), the inverse (If not p, then not q), and the contrapositive (If not q, then not p). Additionally, a biconditional statement (p if and only if q) indicates that both the statement and its converse are true.

Question 1

Points: 1
What is the converse of the statement: 'If a number is divisible by 20, then it is even.'
Explanation
The converse of a statement 'If p, then q' is 'If q, then p'. Here, the conclusion 'it is even' becomes the hypothesis, and the hypothesis 'a number is divisible by 20' becomes the conclusion.
What is the truth value of the statement, If 2x - 5 = 19, then x = 12.
Explanation
Solving the equation 2x - 5 = 19 by adding 5 to both sides gives 2x = 24, and dividing by 2 results in x = 12. Since the conclusion matches the calculated value, the statement is true.
Write the statement 'Vertical Angles are congruent' as a conditional statement.
Explanation
A conditional statement is written in the form 'If p, then q'. In this case, being vertical is the condition (hypothesis) that leads to them being congruent (conclusion).
