Jenni wrote a conditional statement and its converse. Conditional: If two angles are alternate interior angles, then they are co
Tomtit [17]
  1. Yes; alternate interior angles.
  2. A counterexample to dispute the validity of the converse statement is that if two angles are congruent, then they are supplementary angles.

<h3>What is a conditional statement?</h3>

A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, it typically has the form "if P then Q."

<u>Where:</u>

P and Q represent sentences.

<h3>What is a converse statement?</h3>

A converse statement can be defined as a type of statement that is obtained by switching (reversing) the hypothesis and conclusion of a conditional statement. This ultimately implies that, the converse of a statement is obtained by switching (reversing) the hypothesis and  conclusion of a conditional statement.

In this context, we can reasonably infer and logically deduce that Jenni wrote the converse statement properly i.e yes; alternate interior angles.

A counterexample to dispute the validity of the converse statement is that if two angles are congruent, then they are supplementary angles.
