true/truth value
a conditional statement is wether the statement is true or false
truth table

linear pair postulate
states “ if two angles form a linear pair, then the angles are supplementary
segment additional postulate
states “ if point B is on AC and between points A and C, then AB+BC=AC
Angle addition postulate
states “ if point D lies in the interior of <ABC, then m<ABD+ m<DBC=m<ABC
proof
a series of statements and corresponding reasons forming a valid argument is that strays with a hypothesis and arrives at a conclusion
SSS
states “ if three sides of one triangle are congruent to the corresponding sides of another triangle, then the triangles are congruent
CPTC
states that corresponding angles and sides in two congruent triangles are congruent
included angle
the angle formed by two sides of a triangle
SAS
states “ if two sides and the included angle of one triangle are congruent to the corresponding two sides and the included angle of a second triangle, then the triangles are congruent
ASA
states “ if two angles and the included side of one triangle are congruent to the corresponding two angles and the included side of another triangle, then the triangles are congruent
