Alternate Interior Angles:Are non adjacent interior angles that lie on opposite sides of transversal t.
Alternate Exterior Angles: Are non adjacent exterior angles that lie on opposite sides of transversal t.
Consecutive Interior Angles: Are interior angles that lies on the same side of the transversal t.
Transversal: A line that intersects two or more lines in a plane at different points.
Corresponding Angles: Lie on the same side of transversal t and on the same side of lines q and r.
Interior angles: Angles that lie between two transversals that intersect the same line.
Exterior Angles: An Angles formed by one side of a triangle and the extension of another side.
Equidistant: The distance between two lines measured along a perpendicular line is always the same.
Parallel Lines: Coplanar lines that do not intersect.
Parallel Planes: Planes that do not intersect.
Rate of Change: Describes how a quantity is changing over time.
Skew Lines: Lines that do not intersect and are not coplanar.
Truth Value: The truth or falsity of a statement.
Truth Table: A table used as a convenient method for organizing the truth values.
Proof: A logical argument in which each statement you make is supported by a statement that is accepted as true.
Postulate: A statement that describes a fundamental relationship between the basic terms of geometry. They are accepted as true without proof.
Perimeter: The sum of the lengths of the sides of a polygon.
Obtuse Angle: An angle with degree measure greater than 90 and less than 180 degrees.
Midpoint: The point on a segment exactly halfway between the endpoints of the segment.
Line Segment: A measurable part of a line that consists of two points, called endpoints, and all of the points between them.
Line: Is made up of at least two points.
Inverse: The statement formed by negating both the hypothesis and conclusion of a conditional statement.
Inductive Reasoning: Reasoning that uses a number of specific examples to arrive at a plausible generalization or prediction.
Indirect Reasoning: Reasoning that assumes that the conclusion is false and then shows that this assumption leads to a contradiction of the hypothesis like a postulate, theorem, or corollary.
Hypothesis: In a conditional statement, the statement that immediately follows the word if.
Formal Proof: A Two-column proof containing statements and reasons.
Deductive Reasoning: A system of reasoning that uses facts, rules, definitions, or properties to reach logical conclusions.
Converse: The statement formed by exchanging the hypothesis and conclusion of a conditional statement.
Conjecture: An educated guess based on known information.
Conclusion: In a conditional statement. the statement that immediately follows the word then.
Conditional statement: A statement that can be written in if-then form.
Compound Statement: A statement formed by joining two or more statements.
Complementary Angles: Two angles with measures that have a sum of 90 degrees.
Circumference: The distance around a circle.
Angle bisector: A ray that divides an angle into two congruent angles.
Algebraic proof: A proof that is made up of a series of algebraic statements.
Acute angle: An angle with a degree measure less than 90 degrees.
Adjacent Angles: Two angles that lie in the same plane, have a common vertex and a common side, but no common interior points.
