Quiz 1
1. Write the following statement as a conditional. Write the hypothesis and the conclusion.
Glass objects are fragile.Conditional: ___________________________________________Hypothesis: ___________________________________________Conclusion: ___________________________________________
2. Give the truth value for the following conditional. If false, provide a counter example.
If a number is divisible by 9, then it is odd.
Truth value: _________ Counter example (if any): ___________________
Quiz 13. Given the conditional, write the converse, inverse and contrapositive for
this statement.
If you work, then you get paid.
Converse: _____________________________________________
Inverse: ______________________________________________
Contrapositive: _________________________________________
Quiz 2
Use the figure on right to answer Exercises 1–3.1. Name three collinear points. ____, ____, ____2. Name four coplanar points. ____, ____, ____, ____3. Name four noncoplanar points. ____, ____, ____, ____ 4. Find each intersection.a. and plane P _________________b. and plane P _________________c. and ___________________d. plane P and point G _______________
Quiz 2In the figure, are the lines parallel, intersecting, or skew?
5. and _________________________
6. and _________________________
7. and _________________________
Quiz 3In Exercise 1, use the figure and find LM.1. and
X = ________LM = _______
2. Use the figure to find each of the following.a. x _________b. MR ________c. RP ________
Quiz 3Name an angle or angles in the diagram described by each
of the following.3. supplementary to ____________________4. complementary to ___________________5. congruent to ___________________6. a pair of vertical angles ____________________
Biconditionals
Consider the true conditional statement. Write its converse. If the converse is also true, combine the statements as a biconditional. If three points are collinear, then they lie
on the same line.
Angle Measurements
1. If C is in the interior of < ABD and m<ABC = 2x - 1, m<CBD = 3x + 4, and m<ABD = 48, find x and the measure of all the angles. (Draw a picture, label and solve)
2. m<BOX = 2x – 7, m<XOY = 3x + 2. Find x.
X
Y
OB
Bisectors AB bisects CD at E. CE = 3x + 6, ED = 2x + 8.
Find x and CD.
