|---|---|---|---|---|---|
| Acute angle | Angle between 0 degrees and 90 degrees.
🗑
|
||||
| Angle | Two rays connected at their endpoints. The point where the connect is called a vertex.
🗑
|
||||
| Angle bisector | Cuts an angle into 2 congruent angles.
🗑
|
||||
| Collinear points | Points that lie on the same line.
🗑
|
||||
| Congruent angles | Angles that have the same measure.
🗑
|
||||
| Congruent segments | Two segments with the same length.
🗑
|
||||
| Conjecture | A conclusion reached through inductive reasoning.
🗑
|
||||
| Coordinate | Corresponds to a point on a number line.
🗑
|
||||
| Coplanar | Points and lines in the same plane.
🗑
|
||||
| Counter-Example | Enough to disprove a conjecture.
🗑
|
||||
| Inductive Reasoning | Reasoning 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. It bisects the segment.
🗑
|
||||
| Obtuse Angle | Angle higher than 90 degrees.
🗑
|
||||
| Opposite rays | Start at the same point... and go in opposite directions.
🗑
|
||||
| Parallel lines | Coplanar lines that do not intersect.
🗑
|
||||
| Perpendicular lines | Intersect to form right angles.
🗑
|
||||
| Plane | A flat surface that has no thickness. It extends without end in all directions.
🗑
|
||||
| Point | Has no length, width, or thickness, but has a position.
🗑
|
||||
| Postulate | A statement accepted to be true without proof.
🗑
|
||||
| Ray | Part of a line that consists of an initial point and all points on the line that lie on side of the initial point.
🗑
|
||||
| Right Angle | Angle thats exactly 90 degrees
🗑
|
||||
| Segment | A portion of a line between two points, called endpoints.
🗑
|
||||
| Skew lines | Noncoplanar lines. Therefore, they are not parallel and do not intersect.
🗑
|
||||
| Space | The boundless 3-dimensional set of all points.
🗑
