Point

A point denotes to an exact location in space. It is indicated by a dot. It specifies only position and has no length, width, or height. We always name a point by using a capital letter.

Line Segment

A line segment is formed when two points are joined. The two given points are called the end points of the line segment. A line segment is a line with two endpoints.

Line

When we extend line segment through its end points in both direction infinitely (without any end), a line is formed. A line has no ends.

This is line

Ray

When we extend the line segment in one direction beyond its end point, a ray is formed.

This is ray

Note:

A line segment has two end points.

A ray has one end point.

A line has no end point.

Curve

A curve is a line which not straight and drawn without lifting a pencil/pen. A closed curve is a curve that begins and ends at the same point.

Solids Shapes (3 D shapes)

Face The flat side or surface of the solid are known as face or side of the solid

Edge A line along which two faces or surfaces or sides of solid meets.

Vertex/ Corner – A point where 3 or more edges meets.

 Cube No. of Corners = 8 No. of Edges = 12 No. of Faces = 6 Cuboid No. of Corners = 8 No. of Edges = 12 No. of Faces = 6 Sphere No. of Corners = 0 No. of Edges = 0 No. of Faces = 0 Cylinder No. of Corners =0 No. of Edges = 2 No. of Faces = 3 (2 flat face top and bottom and 1 curved face) Cone No. of Corners = 0 No. of Edges = 1 No. of Faces =1 Prism No. of Corners = 6 No. of Edges = 9 No. of Faces = 5 Pyramid No. of Corners = 5 No. of Edges = 8 No. of Faces = 5
