What is a point?
These angles add up to 180 degrees and are not necessarily adjacent.
What are supplementary angles?
These fundamental truths are accepted not proven.
What are postulates?
These tools used for justification in proofs must be proven.
What is a theorem?
p is called the hypothesis and Q is called the
What is the conclusion?
3 points located on the same plane.
What is coplanar?
the supplement of an 50 degree angle.
What is 130 degrees?
A segment is made up of the sum of its smaller parts.
What is segment addition postulate?
this theorem states that the corresponding parts of congruent triangles are congruent.
What is CPCTC?
this statement in a proof is first. It matches the hypothesis of the conditional statements.
What is the given?
this is the intersection when planes intersect
What is a line?
This angle pair shares only a vertex.
what are vertical angles?
this Postulate states that two triangles are congruent if you prove they have an angle that is congruent between two congruent sides.
What is side angle side?
This theorem states two triangles are congruent if all three sides in both triangles are congruent.
What is SSS?
One of the four possible justifications for proving triangles are congruent.
What is ASA, pr AAS or SSS or SAS?
The number of degrees in a straight angle.
What is 180?
These angles share a side and a vertex.
What are adjacent angles?
If M is the mid point of AB then AM= MB.... this is called
What is the definition of a midpoint?
This theorem states two angles that share only a vertex are equal.
What is the vertical angle theorem?
This justification , if it is used, must always logically follow the statement that triangle is congruent.
What is CPCTC?
A bag of 2 red, 3 blue and 7 pink marbles, what is the probability of choosing a red marble?
What is 1/5?
This angle pair is supplementary and adjacent.
What is a linear pair?
The converse of the base angle theorem.
