2. Explain whether the following statement is a valid definition: “A 150° angle is an obtuse angle.” Use the converse, biconditional, and at least one Euler diagram to support your answer.
Answer:
“A 150° angle is an obtuse angle” is not a valid definition. it is not reversible, so its converse is false:
Converse: An obtuse angle is 150º.
Bicoditional: There is no biconditional for this statement because the two hypothesis both need to be true to combine them and make a biconditional.

well....A 150 degree angle is an obtuse angle...this is true, but it is not a valid definition because an obtuse angle is an angle that is over 90 degrees, but less then 180 degrees...so 120 degree angle is also obtuse.
