"I'm not afraid of storms, for I'm learning how to sail my ship." -- Louisa May Alcott Formative #4 Reynolds Geometry 10/12/11 nomen__________________________ Please show work/set-ups 2) a)Underline the hypothesis and circle the conclusion of this statement: If an angle is a right angle, then its measure is 90. b)Is this statement true, if not provide a counterexample: c) What is the converse of this statement? d) Is this converse true, if not provide a counterexample: e) if both the statement and its converse are true, rewrite the statement as a biconditional. 1) Name two angles supplementary to EOD 4) Is this a good definition of a square? Why or why not? A square is a figure with four congruent sides. 5) Name the Property of Congruence that justifies the statement: If A B and B C then A C 3) Sketch and find the equation of a line through the points: A(2, 5) and B(5, -1) “The only thing necessary for the triumph of evil is for good men to do nothing.”-- Edmund Burke 6) What type of angles are each of these? What is their relationship to each other? 52° 128° Drawing not to scale 10. Given point P (3, 7) and Q (-5, 2) find the midpoint of segment PQ 7) solve for x and then find each angle’s measure. (7x – 8)° (6x + 11)° Drawing not to scale 8) Given that angle 1 is supplements with angle 2 and angle 3 is supplements with angle 2 Prove: angle 1 is congruent to angle 3 9 . Given: 1 3 Prove: line a // line b 3) Determine whether the conditional and its converse are both true. If both are true, combine them as a biconditional. If either is false, give a counterexample. If two lines are parallel, they do not intersect. T or F? If two lines do not intersect, they are parallel. T or F?
