Asap see attachment below i'm giving all points i have left and maybe the brainliest !

The answer is (C). We want to use reasoning to show that AD is perpendicular to BC, so we have to use something else in the “if” part of the “if-then” statementto say that the statement is true. You can’t use what you want to prove as your reasoning, which is what it is using for (D). So, the answer is (C).

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
