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: _________________________________________

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.
