Mrs. Rivas International Studies Charter School. 1. How do you write the inverse of the conditional statement below? “If m ∠ 1 = 60°, then ∠ 1 is acute.” a. If m ∠ 1 = 60°, then ∠ 1 is not acute. b. If ∠ 1 is not acute, then m ∠ 1 ≠ 60°. c. If ∠ 1 is acute, then m ∠ 1 = 60°. d. If m ∠ 1 ≠ 60°, then ∠ 1 is not acute 2. What is the contrapositive of the statement below? “If today is Friday, then tomorrow is Saturday.” a. If tomorrow is not Saturday, then today is not Friday. b. If today is Saturday, then tomorrow is not Friday. c. If tomorrow is Saturday, then today is Friday. d. If today is not Friday, then tomorrow is not Saturday
