Part of a line that consists of two points, called endpoints, and all the points on the line between the endpoints.
The ray "AB" consists of the endpoint "A" and all points on line "AB" that lie on the same side of "A" as "B."
The distance between two points "A" and "B," written as "AB," is the absolute value of the difference of the coordinates of "A" and"B."
the process of finding a pattern for specific cases and then writing a conjecture for the general case.
a form of a conditional statement in which the "if" part contains the hypothesis and the "then" part contains the conclusion.
the part of a conditional statement that is formed by negating both the hypothesis and conclusion.
the part that is formed by writing the converse and then negating both the hypothesis and the conclusion.
using facts, definitions, excepted properties, and laws of logic to form a logical argument.
line perpendicular to a plane
if, and only if, the line intersects the plane in a point and is perpendicular to every line in the plane that intersects it at that point.
postulate 11 1/2: (don't ask me how)
through any 3 noncollinear points, there exists exactly one plane
Has numbered statements and corresponding reasons that show an argument in logical order.
alternate interior angles
two angles that lie between the two lines and on opposite sides of the transversal
alternate exterior angles
two angles that lie outside the two lines and on opposite sides of the transversal
consecutive interior angle
two angles that lie between the two lines and on the same side of the transversal
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
the general form of a linear equation in slope-intercept form is 'y=mx+b' where "m" is the slope and "b" is the Y-intercept
the general form of a linear equation in standard form is Ax+By=c, where "A" and "B" are not both zero
when the sides of a polygon are extended, the original angles are the interior angles
when the sides of a polygon are extended, the angles that form linear pairs with the interior angles are the exterior angles
where all the parts of one figure are congruent to the corresponding parts of the other figure
in congruent polygons, the corresponding parts are the corresponding sides and the corresponding angles
an operation that moves or changes a geometric figure in some way to produce a new figure
a segment, ray, line, or plane that is perpendicular to a segment at its midpoint
