Write the converse and the contrapositive to the following statements. (a) (Let $a, b$, and $c$ be the lengths of sides of a triangle.) If $a^{2}+b^{2}=c^{2}$, then the triangle is a right triangle. (b) If angle $A B C$ is acute, then its measure is greater than $0^{\circ}$ and less than $90^{\circ}$

Key Concepts

Conditional Statement

A conditional statement is an 'if-then' structure in logic where one statement (the hypothesis) implies another (the conclusion). These are foundational in mathematics and reasoning because they establish a relationship between two propositions, allowing for logical deductions and proofs.

Converse

The converse of a conditional statement is formed by swapping the hypothesis and the conclusion. It takes the form 'if Q, then P.' Importantly, while the original statement and its converse can both be true, the truth of one does not guarantee the truth of the other, hence each must be proven or examined independently.

Contrapositive

The contrapositive of a conditional statement is obtained by reversing and negating both the hypothesis and the conclusion, resulting in 'if not Q, then not P.' Unlike the converse, the contrapositive is logically equivalent to the original conditional statement, meaning that if the original statement is true, so is its contrapositive, and vice versa.
