1-7 Properties of Equality
Addition: add the same thing to both sides.
Subtraction: Subtract the same thing from both sides.
Division: divide the same thing from both sides.
Subtraction Property: PLUG in something.
Distributive Properties: a(b+c) = ab=ac.
Reflexive Property: a=a, AB=AB, measure of angle b = measure of angle b.
Symmetric: A=B, then B=A, AB=CD, then CD=AB.
Transitive: a=b and b=c, then a=c. LIKE SUBSTITUTION, BUT NO COMBINING LIKE TERMS!!!!
AB is congruent to CD, CD is congruent to EF, then AB is congruent to EF.
Segment AB is congruent to segment CD - Given
Segment CD is congruent to segment EF - Given
Segement AB = segment CD and Segment CD = Segment EF - Definition of Congruence
Segment AB = segment EF - Transitive
Segment AB is congruent to segment EF -
What is the answer to Segment AB is congruent to segment EF?
