Terms | Definitions |
|---|---|
 Node | A point of land mass in graph theory |
| Even Node | A node with an even number of arcs attached |
| Odd Node | a node with an odd number of arcs attached |
| Traversable Network | a network in which all the arcs may be traced exactly once without picking up the tracing instrument ( if you can go through) |
| Coplanar | Lying on the same plane |
| Parallel Lines | Two coplanar lines that have no points in common or are identical |
| Collinear | Lying on the same line |
| Line Segment | A segment with two endpoints |
| Ray | Consists of one endpoint and one point and all the points in between |
| Opposite Rays | Rays going in the opposite direction. Where AB And AC have A in between |
| Between | a point or number in between two other points on the same line if its coordinate is between their coordinates |
| Vertex | A place where two line segments meet ( a point) |
| Convex Polygon | A polygon that is convex, meaning that all segments contain no dents and if you took a straight edge against the segments, they would line up |
| Compound Statement | A sentence that combines two or more statements with some type of connective such as and or if then etc |

| Arc | The lines or Curved lines attached to the nodes |
| Atecedent( Hypothesis) | the "If" clause of a conditional that is also called hypothesis |
| Consequent( Conclusion) | the " then" clause of the conditional statement which is also called the conclusion |
| Instance of a Conditional | a specific case of when the antecedent and consequent are true |
| Counterexample to a Conditional | a specific case for which the antecedent is true but the consequent is false |
| Converse | A conditional statement formed by switching the antecedent and consequent of a given conditional |
| Biconditional | a statement that includes a conditional and its converse. Also called a if and only if statement |

| Scalene Triangle | A triangle with no sides having the same length |
| Arc | Set of points made up by 2 points on a circle |
| Semicircle | Arc whose degree measure is 180 degrees |
| Minor Arc | Arc with measure less than 180 degrees |
| Major Arc | Arc with measure more than 180 degrees |
| Central Angle | When the vertex of an angle is at the center of a circle |
| Zero Angle | Angle whose measure is 0 degrees |
| Acute Angle | Angle whose measure is greater than 0 degrees but less than 90 degrees |
| Right Angle | Angle whose measure is 90 degrees |
| Obtuse Angle | Angle whose measure is between 90-180 degrees |
| Straight Angle | Angle with a measure of 180 degrees |
| Interior of an Angle | A nonzero angle seperates the plane into two sets of points and it that plane it not straight, then the convex set is the interior of the angle |
| Exterior of an Angle | a nonzero angle seperates the plane into two sets of points and if the angle is not straight the nonconvex set is the exterior of the angle |
| Adjacent Angles | Two nonstraight and non zero angles with a common side interior to the angle formed by the non common sides |
| Angle Bisector | the ray in the interior of an angle that divides the angle into two angles of equal measure |
| Complementary Angles | Two angles whose measure sums up to 90 degrees |
| Supplementary Angles | Two angles whose measure sums up to 180 degrees |
| Linear Pair | Two adjacent angles whose non common sides are opposite rays, Supplementary ( pairs make up a line) |
| Vertical Angles | Two nonstraight angles whose union of there sides is 2 lines and the measure of the two angles will be equal |
| Transversal | A line that intersects two or more lines |
| Corresponding Angles | A pair of angles in similiar location in respect to its transversal and each line |
| Alternate Interior Angles | Angle that are on opposite sides of a transversal on the interior of the lines that the transversal intersects |
| Same Side Interior Angles | Angles on the same side of a transversal which are interior and have different vertices |
| Perpendicular | Two segments, rays or lines such that the lines containing them form a 90 degree angle |
| Equidistant | At the same distance |
| Bisector of a Segment | A line, ray or segment that intersects a segment at its midpoint but does not contain the segment |
