This is what collinear means.
What is points on the same line?
100
The first reason on any algebra proof is this ____.
Given
100
Point B is in between point A and point C. They are all on the same line. Therefore AB + BC = AC. What did I use to find this?
What is segment addition postulate?
100
<ABC is bisected by line DB. How did I find out that <ABD = <DBC?
What is definition of an angle bisector?
200
Points that lie on the same plane are said to be this.
What is coplanar?
200
What property is shown?
A=A
What is reflexive property?
200
If B is the midpoint of AC, how did I find that AB=BC
What is definition of midpoint?
200
If <M and <N form a right angle, how do I know that they are complementary?
What is complement theorem?
300
A 98 degree angle can be classified as this type of angle.
What is obtuse?
300
True or False. This would be an example of the transitive property:
If /_A+/_B=180° and /_B+/_C=180°
then
/_A=/_C
False, Congruent Supplements Theorem
300
True/False. Definition of congruence is only used with segment proofs.
False.
300

Vertical Angles Theorem
Complement Theorem
Supplements Theorem
Congruent Supplements Theorem
Congruent Complements Theorem

What is the division or symmetric property?
400
What is reason 4 is the proof?
What is the definition of midpoint?
400
If <X is supplementary to <Y and <X is supplementary to <Z, then <Y is congruent to <Z.
What did I use to find out that <Y is congruent to <Z
What is congruent supplements theorem?
500
