8. $100 Question from Under one Condition Write the statement as a conditional: An acute angle measures less than 90 degrees. What is if an angle is acute, then it measures less than 90 degrees.

9. $200 Question from Under one Condition What is the converse and inverse of the following statement: If ABC is equilateral, then it is isosceles. Converse: If ABC is isosceles, then it is equilateral. Inverse: If ABC is not equilateral, then it is not isosceles.

10. $300 Question from Under one Condition Write the following statement as a conditional, and write its contrapositive. All obtuse angles have measure greater than 90. Conditional: If an angle is obtuse, then it has measure greater than 90. Contrapositive: If an angle does not have measure greater than 90, then it is not obtuse.

11. $400 Question from Under one Condition Write the converse, inverse, and contrapositive of the following conditional. If a triangle is a right triangle, then it has a 90 degree angle. Converse: If a triangle has a 90 degree angle, then it is a right triangle. Inverse: If a triangle is not a right triangle, then it does not have a 90 degree angle. Contrapositive: If a triangle does not have a 90 degree angle, then it is not a right triangle.

12. $500 Question from Under one Condition Write the converse, inverse, and contrapositive of the following conditional, and determine the truth value of each. If two angles have measure 90, then the angles are congruent. Converse: If two angles are congruent, then they have measure 90. Truth Value: False Inverse: If two angles do not have measure 90, then they are not congruent. Truth Value: False Contrapositive: If two angles are not congruent, then they do not have measure 90. Truth Value: False

13. $100 Question from Possible Conclusions Consider the following conditional statement. If the conditional and it’s converse are true, write it as a biconditional. If three points are collinear, then they lie on the same line. Three points are collinear if and only if they lie on the same line.

14. $200 Question from Possible Conclusions Test the following statement to see if it is reversible. If so, write it as a biconditional. If not, write not reversible. A triangle with two sides of equal length is an isosceles triangle. A triangle is an isosceles triangle if and only if it has two sides of equal length.

15. $300 Question from Possible Conclusions If possible, use the Law of Detachment to draw a conclusion. If not write, not possible. If a person goes to the zoo, he or she will see animals. Kayla sees animals. Not possible.

16. $400 Question from Possible Conclusions Use the Law of Syllogism to draw a conclusion. If a polygon is a hexagon, then the sum of its angles is 720. If the sum of the angles of a polygon is 720, then it has six sides. If a polygon is a hexagon, then it has six sides.

17. $500 Question from Possible Conclusions Use the Law of Detachment and the Law of Syllogism to draw a conclusion. If you live in Little Rock, then you live in Arkansas. Levon lives in Little Rock.

24. $200 Question from Prove me Wrong Two pairs of congruent angles in the figure are these. D B A C O What are <DOA & < BOC;,DOB & <AOC

25. $300 Question from Prove me Wrong The value of x is this. What is 30

26. $400 Question from Prove me Wrong If m < 1 = m < 3, order the steps given to prove that m < 2 = m < 4. 12 3 4 1. By the Angle Addition Postulate, m < 3 + m < 4 = 180. 2. Prove: m < 2 = m < 4. 3. By substitution, m < 3 + m < 2 = m < 3 + m < 4. 4. By the Angle Addition Postulate, m < 1 + m < 2 = 180. 5. Given: m < 1 = m < 3 6. m < 1 + m < 2 = m < 3 + m < 4, by the Transitive Property of =. 7. Subtract m < 3 from both sides, and you get m < 2 = m < 4. 5, 2, 4, 1, 6, 3, 7 or 5, 2, 1, 4, 6, 3, 7
