Question | Answer |
point | A location with neither shape nor size |
line | Made up of points and has no thickness or width |
plane | flat surface made up of points that extend infinitely in all directions |
collinear points | points that lie on the same line |
coplanar points | points that lie in the same plane |
line segment | Can be measured and has two endpoints |
ray | part of a line that extends infinitely in one direction |
opposite rays | two rays determined by a point on a line |
intersection | two or more geometric figures is the set of points that they have in common |
postulate | describes a fundamental relationship between the basic terms of geometry |
distance between two points on a line | length of the segment with those points as endpoints |
angle | formed by two noncollinear rays that have a common endpoint |
acute angle | angle measurement is less that 90 degrees |
obtuse angle | Angle measurement is over 90 degrees |
right angle | angle measurement is exactly 90 degrees |
straight angle | same as straight line; angle measurement is exactly 180 degrees |
congruent angles | two or more angles that measure the same length |
supplementary angles | Two angles with measures that have a sum of 180 degrees |
angle bisector | A ray that divides an angle into two congruent angles |
complementary angles | Two angles with measures that have a sum of 90 degrees |
adjacent angles | two angles that lie in the same plane, have a common vertex and a common side, but no common interior points |
linear pair | A pair of adjacent angles whose noncommon sides are opposite rays |
vertical angles | Two nonadjacent angles formed by two intersecting lines |
polygon | A closed figure formed by a finite number of coplanar segments called sides |
convex polygon | A polygon for which there is no line that contains both a side of the polygon and a point in the interior of the polygon |
concave polygon | A polygon for which there is a line containing a side of the polygon that also contains a point in the interior of the polygon. |
n-gon | A polygon with n sides |
equilateral polygon | A polygon with all equal sides |
equiangular polygon | A polygon with all angles that are equal |
regular polygon | A polygon with both sides and angles equal |
