Point, Lines, Planes - Assessment

Front

What is a line in geometry?

Back

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

Front

How many points are needed to define a line?

Back

At least 2 points are needed to determine a line.

Front

What does it mean for points to be collinear?

Back

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

Front

Define a plane in geometry.

Back

A plane is a flat surface made up of points that has two dimensions and extends infinitely in all directions.

Front

What is the relationship between points A, B, and C if they are collinear?

Back

If points A, B, and C are collinear, they all lie on the same line.

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 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 can you determine if three points are collinear?

Back

Three points are collinear if the slope between any two pairs of points is the same.

Front

What is the significance of a point in geometry?

Back

A point represents a specific location in space and has no dimensions.

Front

What are the properties of a plane?

Back

A plane has length and width but no thickness, and it extends infinitely in all directions.
