PROPERTIES OF EQUALITY OR CONGRUENCE

Answers with Step-by-step explanation:

  • MAB = MAB

Answer: This equation demonstrates Reflexive Property. Reflexive Property states that a certain quantity is always equal to itself. So in this scenario, the angle MAB is equal to itself.

  • If AB = CD, then AB + EF = CD + EF.

Answer: This condition demonstrates Addition Property of Equality. It states that whatever is added  to one side of the equation should also be added to the other side of the equation to keep it the same.

  • If AB = CD, then AB - EF = CD - EF

Answer: This condition demonstrates Subtraction Property of Equality. It states that whatever is subtracted to one side of the equation should also be subtracted to the other side of the equation to keep it the same.

  • If m∠A = m∠B and m∠B = m∠C, then m∠A=m∠C.

Answer: This statement demonstrates Transitive Property of Equality.

  • If mAB = mDC + mEF and mEF = mMN, then mAB = mDC + mMN​.

Answer: This statement demonstrates Substitution Property. Substitution Property states that a quantity is equal to another certain quantity, then, the latter can substitute the former in any equation. For example, if x = y, then the value of x can be substituted by y in any equation.
