(1) AC (2) AB (3) ray BA (4) line AC 2. If B is the midpoint of AC , then which of the following must be true? (1) AB > BC (2) AC < BC (3) ½ AC = 2AB (4) 2BC = AC 3. In the figure given, what is the value of x? (1) 20 (2) 40 (3) 80 (4) 100 4. If two adjacent angles form a straight line and the ratio of the larger angle to the smaller is 7 to 3, what is the measure in degrees of the smaller angle? (1) 18 (3) 72 (2) 54 (4) 126 5. If m<COB = m<BOA and m<1 = m<4, which of the following can be used to determine that m<2 = m<3? (1) Addition Postulate (2) Subtraction Postulate (3) Substitution (4) Transitive Property 6.

(1) <3 and <2 are nonadjacent complementary angles (2) <1 and <2 are adjacent and supplementary angles (3) <DBA and <ABC are congruent complementary angles (4) <3 and <ABC are adjacent angles that form a linear pair 8. Find the measure of an angle if its measure is 10 less than three times the measure of its complement. (1) 25 (3) 60 (2) 30 (4) 65 9. Find the midpoint of segment AB given the endpoints A(2a, 3b) and B(4, b). (1) (6a, 4b) (3) (2a+4, b) (2) (a+2, 2b) (4) (a+4, 2b) 10. If two angles are supplements of the same angle, then they must be: (1) adjacent (3) complementary (2) congruent (4) vertical
