Points Lines Planes Flashcard

Front

What is a point in geometry?

Back

A point is a fundamental concept in geometry that represents a location in space. It has no dimensions, meaning it has no length, width, or height.

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions. It has length but no width or height.

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 height.

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.

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 many dimensions does a point have?

Back

A point has zero dimensions.

Front

What are collinear points?

Back

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

Front

What are coplanar points?

Back

Coplanar points are points that lie on the same plane.

Front

What is the intersection of two lines?

Back

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

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at distinct points.
