Postulate #1: Given any two distinct points, there is exactly one (straight) line containing those two points. Postulate #2: Given any three non-collinear points, there is exactly one plane containing those three points. Postulate #3: If a line and a plane share two points, then the entire line lies within the plane.

Basic Geometric Terms. Point – an exact location in space. A point has no dimension. Line – a collection of points along a straight path that extends endlessly in both directions. Line Segment – a part of a line having two endpoints. (read “line segment ”) The length of is denoted . Ray – a part of a line having only one endpoint.
Statements of definitions are always true, as are their converses. Euler diagram for → ( b (a) ) A syllogism is a type of direct proof of the form a b b c Therefore, a c. The statements a b and b c are called the premises of the argument. a c is called the conclusion of the argument, and is often considered to be a theorem.

Ray – directed line segment . Angle – 2 rays that converge on one point . Vertex – where 2 rays meet . Plane – the area in 2 dimensional object
Transposition is a method to isolate the variable to one side of the equation and everything else to the other side so that you can solve the equation. Two methods are covered here: Method 1: Using inverse operations. Method 2: a shortcut trick that allows you to work faster. The following table gives the steps to Isolate a Variable.

Isolating a Variable. Isolating a variable means rearranging an algebraic equation so that a different variable is on its own. The goal is to choose a sequence of operations that will leave the variable of interest on one side and put all other terms on the other side of the equal sign. For example, making x x the subject of the formula y = x ...
