Question | Answer |
---|---|
acute angle | an angle whose measure is between 0 and 90. |
angle | two rays connected cut their endpoints.(the point is where they connect called the vertex) |
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 measure |
congruent segments | segments with the same length |
Conjecture | a conclusion reached by using inductive reasoning |
Coordinate | a point on a line or plane |
Coplanar | points or lines on same plane |
counterexample | is a conclusion reached through inductive reasoning |
inductive reasoning | is based on observed patterns |
line | has no length,no width, or thickness. It extends without end 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 degrees |
opposite rays | starts at the same point and go in opposite direction |
parallel lines | are coplanar lines that do not intresct |
perpendicular lines | lines intersect to form right angle |
plane | is a flat surface that has no thickness. It extends without end in all direction. *at least 3 noncollinear points to name a plane |
point | has no length, width, or thickness just a postition |
postulate | an accepted statement of fact |
ray | is a part of a line that consits of an intital point and all points on the line that lie on one side of the intinal point |
right angle | a angle that mesaure 90 degrees |
segment | the part of the line consiting of two end points and all points between them |
skew lines | lines that do not lie on the same plane; are noncoplanar lines (they are not parallel&dont intersect) |
space | is the boundless 3-d set of all points |
