Points, Lines and Planes

Front

What is a point in geometry?

Back

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

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 does it mean for points to be collinear?

Back

Points are collinear if they lie on the same straight line.

Front

What is the intersection of two lines?

Back

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

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run.

Front

What is a line segment?

Back

A line segment is a part of a line that has two 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

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.

Front

What is a transversal line?

Back

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