Question

match each vocabulary word to its definition.

definitions:

• represents a location in space or an exact location
• a figure in space drawn between two points with one dimension-length
• a part of a line with two endpoints
• a flat surface made up of points that extend infinitely in all directions
• a part of a line that has an endpoint on one end and extends forever on the other end
• form a line and share an endpoint
• points that lie on the same line
• lines that lie in the same plane

vocabulary words:
a. point
b. opposite rays
c. ray
d. line segment
e. collinear points
f. plane
g. line
h. coplanar

Match definitions to terms

• "represents a location in space or an exact location" matches a. point.
• "a figure in space drawn between two points with one dimension—length" matches g. line.
• "a part of a line with two endpoints" matches d. line segment.
• "a flat surface made up of points that extend infinitely in all directions" matches f. plane.
• "a part of a line that has an endpoint on one end and extends forever on the other end" matches c. ray.
• "form a line and share an endpoint" matches b. opposite rays.
• "points that lie on the same line" matches e. collinear points.
• "lines that lie in the same plane" matches h. coplanar.
