Geometry Writing Prompt 1 In the figure below, two parallel lines are crossed by a transversal. The measure of angle 8 is 132
degrees. Write a paragraph explaining whether or not this is enough information to find the measures of
the other 7 angles. If this is enough information, your paragraph should include each angle measure as
well as how you found each. If this is not enough information, explain what other information you would
need in order to find each angle measure. See the grading rubric for all requirements for writing a
paragraph.
(HINT: your explanation should include vocabulary terms such as vertical, linear pair, corresponding,
alternate interior, and alternate exterior.)

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
