Given the conditional statement "If an angle measures 33°, than the angle is acute", what is the CONVERSE?

• If an angle is acute, than the angle measures 33°.

• If an angle does NOT measure 33°, than the angle is NOT acute.

• If an angle is NOT acute, than the angle does NOT measure 33°.

Given the conditional statement "If an angle measures 33°, than the angle is acute", what is the CONTRAPOSITIVE?

• If an angle is acute, than the angle measures 33°.

• If an angle does NOT measure 33°, than the angle is NOT acute.

• If an angle is NOT acute, than the angle does NOT measure 33°.

Either draw a valid conclusion or state "no valid conclusion". If there is a valid conclusion, tell whether the conclusion is by the law of detachment or syllogism: Given: If a quadrilateral has diagonals that bisect each other, then it is a parallelogram. The diagonals of quadrilateral PQRS bisect each other.

• No valid conclusion

• PQRS is a parallelogram, by Law of Detachment

• PQRS is a parallelogram by Law of Syllogism
