Front

What is a point in geometry?

Back

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

Front

Define a line in geometric terms.

Back

A line is a straight one-dimensional figure 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 a point and extends infinitely in one direction.

Front

What is a plane in geometry?

Back

A plane is a flat two-dimensional surface that extends infinitely in all directions.

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 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

How can you name a line?

Back

A line can be named using any two points on the line or a lowercase letter.

Front

What is the significance of point A in a plane?

Back
