| Term | Definition |
|---|---|
| point | a location in space that is represented by a dot and has no dimension |
| line | one dimensional geometric figure that extends in two opposite directions without end |
| plane | a flat surface made up of points that has two dimensions and extends without end and is represented by a shape that ooks like a floor or a wall |
| endpoints | points that represented that ends of a line segment or ray |
| ray | a geometric figure that consists of the endpoint A and all points on line AB that lie on the same side of point A as point B |
| intersection | the set of points two or more geometric figures have in common |
| postulate/axiom | a rule that is accepted without proof |
| midpoint | the point that divides a segment into two congruent segments |
| segment bisector | a point, ray, line, line segment, or plane that intersects a segment at its midpoint |
| convex polygon | a polygon in which no line that contains a side of the polygon contains a point in the interior of the polygon |
| concave polygon | a polygon in which one line that contains a side of polygonal contains a point in the interor of the polygon |
| polygon | a closed plane figure formed by three or move line segments |
| acute angle | an angle that has measured greater than 0 and less than 90 |
| right angle | an angle that has a measure of 90 |
| obtuse angle | an angle that measures greater than 90 and less than 180 |
| straight angle | an angle that has a measure of 180 |
| angle bisector | a ray that divides an angle into two angles that are congruent |
| complemetry angles | two angles whose measure have a sum of 90 |
| supplementary angle | two angles whose measure have a sum of 180 |
| adjacent angle | two angles that share a common vertex and side but have no common interior points |
| vertical angles | two angles whoes sidesb form two opposite pairs of rays |
| undefined terms | wordsthatb do not have a formal definitions but there is agreement about what they mean (point, line, plane |
| colliner points | points that lie on the same line |
| coplanar points | points that lie on the same plane |
| defined terms | terms that can be discribed using known words like point and line |
| segment | consists of two endpoints and all the points between them |
| opposite rays | rays that start at the same point but go away from each other forming a straight line |
| coordinate | a real number that corresponds to a point on a line |
| distance | the absolute value of the difference of two coordinates on line |
| construction | a geometric drawing that uses a limited set of tools, usally a compass and straghtedge |
| congruent segment | line segments that have the same length |
| between | when three points are collinear, one point is between the other two |
| vertex of an angle | the common endpoint of two rays |
| angle | a set of points consisting of two different rays that have the same endpoint |
| sides of an angle | the rays of an angle |
| interior of an angle | the region that contains call the points between the sides of an angle |
| exterior of an angle | angles that form linear pairs with the interior angles of a polygon |
| measure of an angle | the absolute value of the difference between the real numbers matched with the two rays that form the angle on the protractor |
| linear pair | two adjacent angles whose noncommon sides are oppositr rays |
