Understanding Simple Concepts In Geometry
1. Point
 This is point. We name it by any capital letter of the alphabet, e.g., P.
 A point can be made by the tip of your pencil.
 A point is so small that it has to be drawn very carefully. It shows a definite position
 This is a geometrical straight line. It has an arrowhead on both sides to show that we can make it longer on either side
 We mark points on both sides of the line and name the points A, B, etc. now, we can name the straight line AB.
 The points A and B are called the end points of the line segment AB.
 A line segment can be measured with a scale, it has a definite length.
 It has no breadth or thickness.
 AB is a ray. It has one arrowhead to show that it can be made longer from the side of B.
 A ray AB has one end point A. The point A is called the initial point of ray AB.
2. Straight line
A line has no end points, it has no definite length.
Straight lines can be made in any direction.
horizontal straight line.
vertical straight line.
slanting straight line.
We can call it oblique line.
3. Line segment
The straight line between two points is called a line segment.
Here, AB/DC is a line segment.4. Ray
5. Intersecting lines
Lines GH and KL are crossing each other at a point P.6. Curved lines
Curved lines are fun lines and can be made anyway you like.

Measuring Line Segments
Drawing A Line Segment Of A Given Length
To draw a line segment of a given length, say 5 cm, we proceed as per the following steps.
Solids
An object that occupies space is called a solid. Solids are 3 dimensional and not like plane figures. These are some of the solids you already know.
Some examples of solid shapes from our daily life are:
Plane And Curved Surfaces
FACES, EDGES AND VERTICES
DESCRIPTION OF SOLIDS
Closed And Open Figures
Closed figures
Figures that start and end at the same point are called closed figures.
Open figures
Figures that start at one point and end at another point are called open figures.
TANGRAM
 Tangram is old Chinese puzzle consisting of flat pieces of shapes called 'tans'
 Tangram has either 5 or 7 pieces
 Pieces of a tangram can be put together to form different shapes. A 7 piece tangram looks as shown alongside. The pieces can be cut out and interesting shapes like animals, people, and things can be made
CONGRUENT FIGURES
Figures that have the same shape and are of the same size are called congruent figures.
