Intro to 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 geometry.

Back

A line is a straight one-dimensional figure that extends infinitely in both directions and has no thickness.

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?

Back

A plane is a flat surface made up of points that has two dimensions and extends without end.

Front

What are collinear points?

Back

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

Front

What are non-collinear points?

Back

Non-collinear points are points that do not lie on the same straight line.

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 an angle?

Back

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

Front

What is the intersection of two lines?

Back

The intersection of two lines is the point where they cross each other.
