  1. Make a counterexample

    2x>x
    If x=-1, then it will prove the conjecture wrong

    • 2(-1)>-1
    • -2>-1 false
  2. Make a conditional statement for the definition of a right angle

    Right angle- the measure of the angle is 90 degrees
    If it is a right angle, then its measure of the angle is 90degrees
  3. Make a converse statement for the definition of a right angle

    Right angle- the measure of the angle is 90 degrees
    If the measure of a angle is 90 degrees, then it is a right angle
  4. make a inverse statement about the definition of a right angle

    Right angle- the measure of the angle is 90 degrees
    If it is not a right angle, then the measure of the angle is not 90 degrees
  5. wright a contrapositive statement about the definition of a right angle

    Right angle- the measure of the angle is 90 degrees
    If its measure is not 90 degrees, then it is not a right angle
  6. wright a biconditional statement about the definition of a right angle

    Right angle- the measure of the angle is 90 degrees
    a angle is a right angle if and only of the measure of the angle is 90 degrees
  7. Use the Law of Detachment to make a valid conclusion about the ture statement

    If two statements have the same length, then they are congruent. you know that
    BC=XY
    Because BC=XY satisfies the hypothesis of a true congruent statement, the conclusion is also true, so, (segment)BC is congruent to (segment)XY
  8. use the law of syllogism to wright a new conditional statement

    If rick takes chemistry this year, then jessie will be rick's lab partner.
    If jessie is rick's lab partner, then rick will get an A in chemistry
    If rick takes chemistry this year, them he will get an A in chemistry
  9. Identify the property of equality

    2x+5=20-3x Given
    2x+5+3x=20-3x+3x ???
    Addition property of equality
  10. identify the property of equality

    5x+5=20 given
    5x+5-5=20-5 ???
    subtraction property of equality
  11. identify the property of equality

    5x=15 Given
    5x/5=15/5 ???
    Division property of equality
  12. identify the property of equality

    -4(11x=2)=80 Given
    -44x-8=80 ???
    Distributive property of equality
  13. If you saw m<1=90 degrees and m<2=90 degrees as a statement, what would you put for a reason?
    definition of right angle
