Points, Lines, Planes, & Measuring Segments

Front

What is a point in geometry?

Back

A point is a location that has no size, represented by a dot.

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions.

Front

What is a plane in geometry?

Back

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

Front

What are collinear points?

Back

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

Front

What is the intersection of two planes?

Back

Two planes intersect at a line.

Front

What is the intersection of two lines?

Back

Two lines intersect at a point.

Front

Define a segment in geometry.

Back

A segment is a part of a line that is bounded by two distinct 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

How do you measure a segment?

Back

To measure a segment, use a ruler to find the distance between its two endpoints.

Front

What is the distance formula?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²) for points (x1, y1) and (x2, y2).
