are two line that intersect to form right angles of a segment is a line, segment or ray that is perpendicular to a segment at its midpoint is a ray that divides an angle into two congruent angles
Deductive
Reasoning is a process of reasoning logically from given facts to a conclusion.
Addition
Property of equality
if a=b then a+c=b+c Subtraction
Property of equality
if a=b then a-c=b-c Multiplication
Property of equality
if a = b then ac = bc Division
Property of equality
if a=b then a/c = b/c c≠0
Substitution
Property– if a=b, then b can replace a in any expression
Distributive Reflexive
Property – a(b+c) = ab + ac
Property AB = AB Symmetric Property if AB = CD then CD = AB Transitive Property if AB = CD & CD = EF then AB = EF
