Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions with no endpoints.

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What is a ray in geometry?

Back

A ray is a part of a line that starts at one endpoint and extends infinitely in one direction.

Front

How do you identify parallel lines in a diagram?

Back

Parallel lines can be identified by looking for lines that are equidistant and never intersect.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is the symbol for parallel lines?

Back

The symbol for parallel lines is '||'.

Front

What is the symbol for perpendicular lines?

Back

The symbol for perpendicular lines is '⊥'.
