a. The volume would be three times the original

b. The volume would be twice the original

c. The volume would be eight times the original

d. The volume would be four times the original .

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
