What are coplanar points

The video tutorial explains the concepts of collinear and coplanar points in geometry. It describes how collinear points lie on the same line, while coplanar points lie on the same plane. The teacher uses a box or a sheet of paper as a metaphor for a plane, which requires at least three points. The lesson includes examples to illustrate these concepts and concludes with a reminder about homework.

What does it mean for points to be collinear?

• They lie on the same plane.

• They lie on the same line.

• They are equidistant from each other.

• They form a triangle.

How can a plane be best visualized according to the teacher?

• As a cube that extends indefinitely.

• As a line that stretches infinitely.

• As a sheet of paper that extends indefinitely.

• As a circle that expands forever.

How many points are needed to define a plane?

• Five points

• Two points

• Four points

• Three points

What is the term for points that lie on the same plane?

• Concurrent

• Convergent

• Collinear

• Coplanar

In the example given, which points are confirmed to be coplanar?

• Points A, B, and C

• Points D and E

• Points B, C, and D

• Points A, D, and E
