Elementary Geometry: Line and Angle Relationships Flashcards
What is a set?
Any collection of objects known as elements.
If all of the elements of set A are also in set B.
- Set A is known as
- Set B is known as
- Set A is a subset of B.
2. Set B is a superset of A.
A set of words and/or symbols that can be classified as either true or false is called a
Statement
A letter that represents a number
Variable
A statement that can either be considered true or false such as x+6=5 is known as
Open Statement
What is formed when combining two statements?
Compound Statement
A conjunction (P and Q) is true when?
If an only if P and Q are both true.
A disjunction (P or Q) is true when?
If either P OR Q is true.
The statement “if P, then Q” is known as a:
“If the angle is a right angle, it measures 90 degrees
Conditional Statement
In the conditional statement “If P, then Q”:
- P is the
- Q is the
- Hypothesis
2. Conclusion
Reasoning
A process based on experience and principles that allows one to reach a conclusion.
Intuition
An inspiration leading to the statement of a theory.
Induction
An organized effort to test and validate the theory
Deduction
A formal argument that proves the tested theory
Premise
A statement used to justify a conclusion.
When points are on the same line they are said to be
Collinear
Vertex
The point at which two sides of an angle meet.
