# Assuming that statements 1 and 2 are true, draw a valid conclusion if possible.1) If two angles are both right angles, then the angles are congruent.2) ∠ R and ∠ S are not congruent.C) ∴ ? _________ _____________

To determine

To find:

The valid conclusion.

Explanation

The first statement is, if two angles are both right angles, then the angles are congruent is conditional statement that is assumed to be true, its contra positive statement, if not Q, then not P must also be true.

That means “if two angles are not congruent, then the angles are not both right angles” will be true.

The second given statement satisfies the first part of the contra positive statement that is
