 Question
Acute angle?   Angle less than 90 degres
Angle?   formed by two rays connected by the same endpoint.
Angle bisector   a ray that divides an angle into two congruent angles.
collinear points   lie on the same line
congruent angles   angles that have the same measures
congruent segments   segments with the same length
conjecture   a conclusion reached by using inductive reasoning
coordinate   a specific point on a number line or a plane
coplanar   points and lines in the same plans
counterexample   something that disproves a conjecture
inductive reasoning   something that is reached through examples and the process of elimination
line   has no length,width,or thickness. it extends without ending in two directions
midpoint   a point that divides a segment into two congruent segments
obtuse angle   angle more than 90 degrees and less than 180 degress
opposite rays   start at the same point but go in opposite directions
parrelel lines   coplanar lines across from each other but will never meet
perpendicular lines   lines that intersect to form roght angles
plane   flat surface that has no thickness. it extends without end in all directions
point   no length,width,or thickness, but has a position
postulate   an accepted staement of fact
ray   part of a line that consists of an initial points and all points on the line that lie on one side of the initial point.
right angle   90 degree angle
segment   the part of a line consisting of two points
skew lines   noncoplanar lines that never intersect and are not parallel
space   the set of all points
