Shapes and Patterns
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
