Question | Answer |
---|---|
adjacent angles | two angles that lie in the same plane and have a common vertex and a common side but no common interior points |
linear pair | a pair of adjacent angles with noncommon sides that are opposite rays (form a line) |
vertical angles | two nonadjacent angles formed by two intersecting lines. (congruent) |
complementary angles | two angles with measure that have a sum of ninety |
supplementary angles | two angles with measures that have a sum of 180 the angles in a linear pair are supplementary |
undefined terms | terms that can only be explained by the use of examples or descriptions exactly 1=one and only one |
point | a location it has nieether shape or size named by capital letter (point A) |
line | made up of points has no thickness or width exactly one line through many points named by: letters representing two points on the line or a lower case script letter (line m) |
plane | a flat surface made up of points that extend infinately in all directions. exactly one plane through any three points not on the same line. named by: a capital script letter or by the letters naming three points that are not all on 1 line |
collinear | points that lie on the same line |
noncollinear | points that do not lie on the same line (can use these points to name a plane) |
coplane | points that lie on the same plane |
noncoplanar | points that do not lie in the same plane |
dimension | point has no dimension |
intersection | two or more geometric figures is the set of points they have in common 2 lines intersect at a point |
definitions/defined terms | these are explained by undefined terms or other defined terms |
space | boundless three dimensional set of all points. contains lines and planes |
