TWO LINES ARE COPLANAR

Two lines can always be connected by a plane. The trees are lines and the are connected by a single plane.

Always True

TWO LINES INTERSECT AT

ONE POINT

The antenna of the car represents the line and the top of the car represents the plane that the line intersects in a point.

Sometimes True

The fence is a plane, and the ridge is the line that intersects the plane on a line. Which means that not all lines intersect planes at a point.

TWO PLANES

INTERSECT AT A LINE

The small roof plane intersects the square house plane on a line.

Sometimes True

The two planes represented by columns will never intersect therefore they will never intersect on a line.

TWO PLANES INTERSECT IN A

SINGLE POINT

This statement is never true because when two planes intersect it makes a line, if planes always intersect in a line then it is impossible for them to intersect at a point.

Never True

PLANES HAVE AN EDGE

This statement is never true because planes go on and on forever so there are no edges on a plane.

Never True

TWO POINTS ARE

COLLINEAR

If you pick any two points any where, no matter their distance or height there will always be a line that goes straight through both of them.

Always True

THREE POINTS ARE COLLINEAR

The gutters on the street make three points, and those three points make a line.

Sometimes True

The tree flowers are points that don’t make a line, so three points ,ay or may not be coplanar.

THREE POINTS ARE

COPLANAR

If you take any three points the will always be a plane that connects all of them. All three flowers can be connected by a plane.

Always True

FOUR POINTS ARE

COPLANAR

All four wheels of the car lie on the same plane.

Sometimes True

Three of the flowers make a plane, but the forth flower is all alone.

A POINT IS A SMALL

FILLED CIRCLE

A point is an undefined object, meaning it has no mass, so it can’t be anything (including a small filled circle).

Never True
