TermDefinition
Angle A geometric figure formed by two rays that connect at a single point or vertex.
Intersecting lines Intersecting lines are lines that cross or meet at some point.
line A line is a straight one-dimensional figure that extends forever in opposite directions.
line segment A line segment is a part of a line that has two endpoints.
Parallel Two or more lines are parallel when they lie in the same plane and never intersect. These lines will always have the same slope.
Point A point is a location in space that does not have size or shape.
Point of Intersection A point of intersection is the point where two intersecting lines meet.
Ray A ray is a part of a line that has one endpoint and continues indefinitely in one direction.
