Step 1: State the definition of conditional and biconditional statements
Symbolically Conditional statement becomes:
P ⇒ Q
BiConditional statement becomes:
P ⇔ Q
Step 2: Choose the right respoinse for 1,2,3, 4, and 5
The truth table for a biconditional statement is as shown below
In this case,
[tex]\begin{gathered} P=\text{''An angle is acute''} \\ Q=\text{''It's measure is less than 90 degr}ees\text{''} \end{gathered}[/tex]
Therefore,
1) Conditional: An angle is acute
2) then: It's measure is less than 90 degrees
3) if an angle measures less than 90 degrees, then it is acute
4) the conditional and the converse are true
5) so the biconditional is true
