Front

What is a point in geometry?

Back

A point is a specific location in space that has no size or dimension.

Front

What is a line in geometry?

Back

A line is a straight path that extends infinitely in both directions with no endpoints.

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

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

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 perpendicular lines?

Back

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

Front

What does it mean if lines are neither parallel nor perpendicular?

Back

It means the lines intersect at an angle that is not 90 degrees and are not equidistant.

Front

How can you identify a right angle?

Back

A right angle can be identified by its 90-degree measurement, often marked with a small square.

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.
