Holly wrote the statement Polygon R S T U V is regular if it has congruent sides and congruent angles. Which statements are true regarding her work? Choose three correct answers.

“P is true if Q” means “If Q, then P.” Here, the hypothesis is that polygon R S T U V has congruent sides and congruent angles, so A is true. The conclusion is that the polygon is regular, making D true, and the statement is conditional, making B true. Choice E is not equivalent: it says congruent sides alone imply congruent angles.
