Grade 6+ Lesson s1-l1

Explanation: The best way to understand geometry is by looking at some definitions. Take turns and read each definition for easy understanding.

Definition: Point

A point is an exact location or position with no size. It means the point has no width, no length, or no depth.
There are different types of points in geometry:
Collinear Points,Non-Collinear Points,Coplanar Points and Non-coplanar Points.

$1$

Explanation:

In this image, it shows the representation of the point.

Definition: Collinear Points & Non-Collinear Points

Points on a line are collinear. Points not on a line are non-collinear.

$2$

Explanation:

E, F, & G are collinear points, and H, I are non-collinear points.

Definition: Coplanar Points & Non-coplanar Points

Points on the same plane are coplanar, while those not on the same plane are non-coplanar.

$3$

Explanation:

E and F are planar, whereas points G and H are coplanar. They intersect the plane.

Definition: Line Segment

A-line segment refers to a straight and limited line portion with two endpoints and a measurable length.
It includes all the points between these endpoints and has a measurable length.
A line segment is usually represented by the bar symbol (—) on top of the endpoints.

$4$

Explanation:

In this image, the line segment has endpoints C and D . It can be denoted by the \$\bar "CD"\$.
