vocabulary project


acute angle less than 90 degrees
angle made of 2 rays connected at their endpoints, the point where they connest is the vertex
angle bisector cutting angle into two congruent angles
collinear points points that lie on the same line
congruent angles angles with the same measurements
congruent segments two segments with the same length "~ over = sign" means " congruent to"
conjecture a conclusion reached through inductive reasoning(remember the conjecture seems, but it is unproven)
coordinate The coordinate of a point ios its distance and direction from the origin of a number line
coplanor points & lines in the same plane
counterexample a single couter example is enough to disprove a conjecture
inductive reasoning is reasoning based on ibserved patterns (we assume the observed pattern will continue)
line has no length, width, or thickness. It extends in 2 directions
midpoint a point that divides a segment into two congruent segments
obtuse angle more than 90 degrees
opposite rays starts at the same point and goes in the opposite direction
parallel lines are planes that do not intersect
perpendicular lines lines that intersect to form right angles
plane is a flat surface that has no thickness. It extenbd without end in all directions
point has no length width or thickness but has a position
postulate statement accepted to be true without proof
ray a part nof a line that consist of an intial point and all points on the line that liee on side of the initial point
right angle exactly 90 degrees
segment a portion of a line
skew lines are noncoplanor lines therefore they are not parallel and do not intersect
space 3 dimensional set of all points boundless
