HW#9 page 201 / 2 – 9 , 16 – 22 Name ____________________________________________ Use the Triangle Sum Conjecture to determine each lettered angle in problems 2 – 5. Find the missing angle measures Richard Sudo Tuesday, September 29, 2015 4:10:24 PM CT 00:19:e3:4a:d2:21 16. Write a proof using algebra to explain why each angle of an equiangular triangle measures 600 In Exercises 17 – 21, tell whether the statement is true or false. For each false statement, explain why it is false or sketch a counterexample. 17. If two sides of one triangle 18. If two angles in one 19. If a side and an angle in are congruent to two sides in triangle are congruent to two one triangle are congruent to a another triangle, then the two sides in another triangle, then side and an angle in another triangles are congruent. the two triangles are triangle, then the two triangles congruent. are congruent. 20. If three angles of one triangle are congruent 21. If three sides of one triangle are congruent to three angles in another triangle, then the two to three sides in another triangle, then the two triangles are congruent. triangles are congruent. 22. What is the number of stories in the tallest house you can build with two 52 card decks? How many cards would it take? Richard Sudo Tuesday, September 29, 2015 4:10:24 PM CT 00:19:e3:4a:d2:21
