Question | Answer |
---|---|
acute angles | an angle that is less than 90 degress |
congruent angles | angles that have the same measurement |
coplanar | points and line in the same plane |
midpoint | the middle of a line |
perpendicular lines | intersect to form right angles. |
ray | is a part of a line that consist of an intial point and all points on the line that lie on one side of the intial point |
space | is the boundless three dimensional set of all points. |
angle | two rays that are connected at their endpoints. |
congruent segments | two segments with the same length. |
counterexample | an example or fact that is inconsistent with a hypothesis and may be used in argument against it |
obtuse angle | angle thats more than 90 degrees |
plane | a plat surface that has no thickness. it extends in all directions |
right angle | an angle that is exactly 90 degrees |
angle bisector | ray that divides an angle into two congruent angles |
conjecture | is a conclusion reached by using inductive reasoning |
inductive reasoning | a type of reasoning that reaches conclusions based on a pattern of specific examples or past events. |
opposite rays | are collinear rays with the same endpoint. they form a line |
point | has no length, width, or thickness, but has a position. LOCATION |
segment | the part of a line consisting pf two points, called endpoints, and all points between them |
collinear points | points that lie on the same line. |
coordinate | Any of a set of two or more numbers used to determine the position of a point, line, curve, or plane in a space of a given dimension with respect to a system of lines or other fixed references. |
line | has length, but no width or thickness. it extends without end in two directions |
parallel lines | are coplanar lines that do not intersect |
postulate | a statement accepted to be true without proof |
skew lines | are noncoplanor lines, not parallel, not intersect |
