Question | Answer |
---|---|
Point | Undefined term in Geometry, a specific location. Has no dimension and is represented by a dot. |
Line | Undefined term in Geometry. A connected straight path. It has no thickness and it continues forever in both directions. |
Plane | Undefined term in Geometry. A flat surface. It has no thickness and it extends forever in all directions. |
Space | The set of all points. |
Segment | A portion of a line consisting of 2 points (called endpoints) and all the points between them. |
Ray | A portion of a line that starts at a point (the endpoint) and continues forever in one direction. |
Opposite Ray | Two rays with a common endpoint that point in opposite directions and form a straight line. |
Collinear | Points on the same line |
Non-Collinear | Points not on the same line |
Coplanar | Points on the same plane |
Non-Coplanar | Points not on the same plane |
Parallel Lines | 2 lines that are coplanar and do not intersect |
Perpendicular Lines | Lines that intersect at right angles |
Skew Lines | Lines that are non-coplanar and do not intersect |
Intersection | The set of points shared by two geometric figures |
