ignacio wants to prove that triangle ABC is congruent to triangle DCB. he says that he knows line AC is congruent to line DB because diagonals in rectangles are congruent. what rule can he use to prove that line BC is congruentto line BC?

Question

Pythagorean Theorem
Distributive property
Reflexive property
HL Theorem

Answer 1

Ignacio can use the Reflexive Property to prove that line BC is congruent to line BC. The Reflexive Property states that any geometric quantity is congruent to itself, which means that line segment BC is congruent to line segment BC.

So, the answer is: Reflexive property.
