points, planes, rays, lines, and segments

Front

What is a point in geometry?

Back

A point is a specific location in space that has no size, dimension, or shape. It is usually represented by a dot and labeled with a capital letter.

Front

Define a line in geometry.

Back

A line is a straight one-dimensional figure that extends infinitely in both directions. It has no endpoints and is usually represented with arrows on both ends.

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints. It is the shortest distance between those two points.

Front

What is a ray?

Back

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

Front

What does it mean for points to be collinear?

Back

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

Front

What does it mean for points to be coplanar?

Back

Coplanar points are points that lie on the same plane.

Front

What is a plane in geometry?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions. It has no thickness.

Front

How do you denote a line segment?

Back

Front

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

Back

A line extends infinitely in both directions with no endpoints, while a line segment has two specific endpoints.

Front

What is the notation for a ray?

Back

A ray is denoted by its endpoint and another point on the ray, for example, @@ ay{AB}@@ starts at point A and passes through point B.
