A line is different from a ray because:
A line has two endpoints, while a ray has only one
A line extends infinitely in both directions, while a ray extends infinitely in one direction
A line stops at a point, while a ray does not
A line is shorter than a ray
Answer explanation
A line extends infinitely in both directions, while a ray has one endpoint and extends infinitely in one direction. This distinction is key in understanding their definitions in geometry.

What do we call a part of a line that has two endpoints?
Ray
Line
Line Segment
Point
Answer explanation
A line segment is defined as a part of a line that has two distinct endpoints. Unlike a ray or a line, which extend infinitely, a line segment is finite and clearly defined by its endpoints.

If two lines never meet no matter how far they are extended, they are called:
Perpendicular lines
Intersecting lines
Parallel lines
Diagonal lines
Answer explanation
Two lines that never meet, regardless of how far they are extended, are defined as parallel lines. This distinguishes them from perpendicular, intersecting, and diagonal lines, which either meet or cross each other.

A point represents:
A location in space
A direction
A moving object
A type of line
Answer explanation
A point is defined as a specific location in space with no dimensions. It does not represent a direction, a moving object, or a type of line, making "A location in space" the correct choice.

Two lines that cross each other at a 90-degree angle are called:
Parallel lines
Perpendicular lines
Skew lines
Diagonal lines
Answer explanation
Two lines that cross each other at a 90-degree angle are known as perpendicular lines. This term specifically describes the relationship between the two lines, distinguishing them from parallel, skew, or diagonal lines.
