Points, Lines, and Planes
Two lines intersect on this (if they intersect at all).
What is a point?
This is a pair or group of angles whose measures add up to 180 degrees.
What are supplementary angles?
This kind of reasoning uses mathematical laws, theorems, postulates, and properties to prove statements.
What is deductive reasoning?
If triangle ABC is congruent to triangle GHI, then all of these are congruent (two words).
What are corresponding parts?
What is collinear?
Two adjacent angles whose measures add up to 180 are these (as specific as possible).
What is a linear pair?
"If you pass the final, then you will pass the class. Johnny passed the final. Therefore, Johnny passed the class!" This is an example of this law.
A set of triangles with two consecutive sides and a NON-INCLUDED angle congruent are referred to as this (two possible answers).
What are donkey triangles?
OR
What is the ambiguous case?
These are lines that do not intersect, but are not parallel.
What are skew lines?
Angles on opposite sides of intersecting lines are this, and they are always congruent.
What are vertical angles?
This is the first step in any proof.
What is the given?
This property states that a measure of a segment is equal to itself.
What is the reflexive property?
If M is between A and B, this would state that AM+MB=AB.
What is the segment addition postulate?
If the measure of angle A is 80 degrees, and the measure of angle B is 10 degrees, then angle A and angle B are this.
What is complementary?
"All dogs are mammals. All mammals have hair or fur. Therefore, all dogs have hair or fur." This is an example of this logical law.
What is the law of syllogism?
In an isosceles triangle, these angles are congruent.
What are the base angles?
In the image, give another name for line n (multiple possible correct answers).
What is line AB or BA?
OR
What is line AC or CA?
OR
What is line BC or CB?
In the image, if the measure of angle RST is 40 degrees, and the measure of angle RSV is 55 degrees, this is the measure of angle TSV.

What is 15 degrees?
Statement A: "If I go to the store, then I will buy eggs."
Statement B: "If I didn't buy eggs, then I didn't go to the store."
Statement B is this of Statement A.
What is the contrapositive?
In the image, the triangles are congruent by this congruence postulate/theorem.
What is the AAS theorem?
