Answer 1

Answers:

• A) Definition of right angles
• B) Substitution
• C) Definition of congruence

=========================================

Explanation:

• A) The term "right angle" is another way of saying "90 degree angle". This is a definition. Think of a definition in a dictionary.
• B) The substitution property allows us to replace one thing for another, as long as the two things are equal. The transitive property works as a similar idea.
• C) If two angles have the same measure, then they are congruent. This is the definition of congruence (or one form of it).
