|---|---|---|---|---|---|
| Line | Connected points that go forever in 2 directions
🗑
|
||||
| Angle | 2 rays or 2 line segments with a shared vertex
🗑
|
||||
| Parallel | 2 lines that are in the same plane that never intersect.
🗑
|
||||
| Vertical | The angles opposite of each other when 2 lines intersect. They share a vertex and are congruent.
🗑
|
||||
| Line Segment | Connected points that have a distinct beginning and ending point
🗑
|
||||
| Acute | An angle that is between 0 and 90 degrees; not including 90 degrees
🗑
|
||||
| Intersecting | 2 lines that cross at single point
🗑
|
||||
| Complementary | 2 angles whose sum of measure equals 90 degrees
🗑
|
||||
| Ray | Connected points that have a distinct beginning point and continue forever in one direction
🗑
|
||||
| Obtuse | An angle that measures between but does not include 90 and 180 degrees
🗑
|
||||
| Perpendicular | 2 lines that cross at a single point forming 90 degree angles
🗑
|
||||
| Transversal | The line that crosses parallel lines forming 8 angles
🗑
|
||||
| Right | An angle that measures exactly 90 degrees
🗑
|
||||
| Corresponding | Angles that are on the same side of a transversal and in the same location on different parallel lines; they are congruent
🗑
|
||||
| Alternate Interior | Angles that are on opposite sides of the transversal but inside the parallel lines; they are congruent
🗑
|
||||
| Straight | An angle that measures exactly 180 degrees
🗑
|
||||
| Vertex | A distinct point where lines intersect or angles originate
🗑
|
||||
| Supplementary | 2 angles whose sum or measure equals 180 degrees
🗑
|
||||
| Alternate Exterior | Angles that are on opposite sides of the transversal and outside of the parallel lines; they are congruent
🗑
|
||||
| Line Relationship | The way 2 lines perform together, such as parallel, perpendicular, or intersecting
🗑
|
||||
| Angle Relationship | The way 2 angles perform together, such as vertical, adjacent, supplementary, etc.
🗑
|
||||
| Adjacent | 2 angles that are side by side, share a vertex, and share one side
🗑
