Geometry

Geometry in English derives from Greek word :                             
Geo- earth and metron- measurement

According to historians, the geometrical ideas shaped up                        
in ancient times, probably due to the need in art, architecture and measurement. These include occasions when the boundaries of cultivated lands had to be marked without giving room for complaints. Construction of magnificent palaces, temples, lakes, dams and cities, art and architecture propped up these ideas.

  
For competitive exams we can divide the geometry sections into the following chapters:
1.  Lines and Angles.
2. Triangles
3. Polygons
4. Quadrilaterals
5. Mensuration
6. Co-ordinate Geometry
7. Trigonometry

For basic concepts and theories refer only NCERT Class 6-10 mathematics, rest you need to practice. More you practice more you remember. Always get your basics clear otherwise practice doesn't matter.
Books you can refer to for practicing:
