#1.1 Points, Lines, and Planes

Front

What is a point in geometry?

Back

A point is a specific location in space that has no dimensions, represented by a dot.

Front

Define a line in geometric terms.

Back

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

Front

What is a plane in geometry?

Back

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

Front

What does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

How do two lines intersect?

Back

Two lines intersect if they cross each other at a single point.

Front

What is the difference between intersecting lines and parallel lines?

Back

Intersecting lines cross at one point, while parallel lines never meet and are always the same distance apart.

Front

What is the significance of a line segment?

Back

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

Front

What does it mean for a line to be named with a letter?

Back

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

Front

What is the relationship between a line and a plane when they intersect?

Back

When a line intersects a plane, it does so at all points along the line that lie within the plane.

Front

What is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at different points.
