The shortest distance between two points is called...

• g) A triangle
• c) A line segment
• f) A polygon
• e) A point

A line is different from a line segment because:

• a line segment extends indefinitely in one direction
• c) A line extends indefinitely in both directions
• a line has one endpoint
• a line can be curved

Two lines that do not meet at any point are called:

• g) Concurrent lines
• f) Collinear lines
• e) Skew lines
• b) Parallel lines

A ray has:

• One endpoint and extends indefinitely in two directions
• A fixed length with no endpoints
• Two endpoints and extends indefinitely in one direction
• a) One endpoint and extends indefinitely in one direction

A simple closed curve made up of only line segments is called:

• A circle
