Points Lines and Planes

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, defined by any two points on it.

Front

What is a plane in geometry?

Back

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

Front

How can a line be named?

Back

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

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

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

Back

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

Front

What is a ray in geometry?

Back

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

Front

What is the significance of a lowercase letter in naming a plane?

Back

A lowercase letter is used to denote a specific plane in geometric terms.

Front

How do you identify collinear points from a set?

Back

Collinear points can be identified if they can be connected by a single straight line.

Front

What is the notation for a line segment?

Back

A line segment is denoted by the endpoints with a line over them, e.g., segment AB is written as AB.
