Intro to Points, Lines and Planes

Front

How many points do you need to make a line?

Back

At least 2 points are needed to define a line.

Front

Name two points collinear to Point K.

Back

Collinear points are points that lie on the same line. For example, if Point K is on a line, then Points J and L can be collinear with Point K.

Front

An example of coplanar points.

Back

Coplanar points are points that lie on the same plane. For example, Points A, F, and E are coplanar.

Front

A line is named by...

Back

A line can be named by any 2 points on the line or by a lowercase script letter.

Front

Points that lie on the same line are _________.

Back

Collinear.

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 and has no endpoints.

Front

What is a plane in geometry?

Back

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

Front

Define collinear points.

Back

Collinear points are three or more points that lie on the same straight line.

Front

Define coplanar points.

Back

Coplanar points are points that lie on the same plane.
