Front

What is a Plane?

Back

A flat, two-dimensional surface that extends infinitely in all directions.

Front

What is a Line?

Back

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

Front

What is a Line Segment?

Back

Front

What is a Point?

Back

A specific location in space that has no size or dimension.

Front

How do you find the length of a line segment?

Back

Subtract the coordinates of the endpoints and take the absolute value.

Front

What is the Midpoint of a line segment?

Back

The point that divides the segment into two equal parts.

Front

How do you calculate the Midpoint of two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

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.
