Chapter 2 Flashcards
What is the symmetric property of equality/congruence?
A=B therefore B=A
What is the transitive property of equality/congruence?
A=B and B=C then A=C
What is the distributive property?
A(B+C)= AB+AC
What is a proof?
A convincing argument that uses deductive reasoning to logically show why conjecture is true
What is a two column proof?
It lists the statements on the left and the reasons on the right
What is the vertical angle theorem?
If angle 1 and angle 2 are vertical angles then angle 1 is congruent to angle 2
What is the congruent supplements/complements theorum?
If angles one and two are supplements and one and three are supplements then angle two and three are congruent
What is the right angle theorem?
Right angles are congruent
What is the congruent supplement theorem?
If two angles are supplementary and congruent then each is a right angle
What is the reflexive property of equality/congruence?
A=A
