Question | Answer |
acute angle | an acute is an angle whose mesure is between 0 and 90. |
angle | an angle is formed by two rays with the same endpoint. the rays are side of the angle and comon endpoint is the vertiz of the angle. |
angle bisector | an angle bisector is a ray that divides an angle into two congruent angles. |
collinear points | points that lie on the same line. |
congruent | anglesangles that have the same mesure |
congruent segments | segments that have the same lenth |
conjectur | a conclusion reach by inductive resoning |
coordinate | |
coplanar | coplaner are figure in the same plase. |
counterexample | a statment that particular example or instence of the statement that makes the statment false. |
inductive reasoning | a type of resoning that reaches conclusions based on a pattern of specific examples or past events. |
line | a line is undefined. you can think of a line as a serious of points that extend in two directions with out an ending point. |
midpoint | the point that divide thqt divides the segment into two congruent segments |
obtuse angle | an obtuse angle is an angle whosemesure is between 90 and 180 |
oppoosite rays | oppisite rays are colinear rays with the same endpoint the form a line. |
parel lines | two lines are parallel if they lie in the same plane and do not intersect. |
perpendicular lines | lines that intersect and form right angles. |
plane | a plane is undefind. a plane contains maney lines and extends without end in the directions od its lines.p |
point | a point has no size and no location |
postulare | an acceoted statement or fact |
ray | a ray is a point of a line consisting of one endpoint. |
right angle | a right anngle is an angle whose mesure is 90 |
segment | a segment is the point of the line that consist of two points. |
skew lines | lines that do not lie on the same plane |
space | space is the set of all points |
