Test 1 Review Geometry Thursday 9/9/10

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 1 3.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 2 In the figure, are the lines parallel, intersecting, or skew? 5. and _________________________ 6. and _________________________ 7. and _________________________

Quiz 3 In 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 3 Name 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.
