Points, Lines, Planes, Distance, and Midpoint

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

What is 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 by two points on the line.

Front

What is a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints. It has a definite length.

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. It has one endpoint.

Front

What is a plane in geometry?

Back

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

Front

How do you find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint M is calculated using the formula: M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Front

What is the definition of a ray?

Back

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

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 and a finite length.
