Advance maths for SSC CGL,SSC CGL GEOMETRY :- GEOMETRY is a major topic for all the government exams like SSC CGL,SSC CHSL,RAILWAY,CAT,XAT,SNAP ect.Most of the questions are asked from geometry in each and every exam.In all of our geometry sessions we will disuss all the basics theory and will solve problem on each and every theory. If the basics are clear geometry becomes very easy and intersting topic for everyone.so lets make geometry easy and interesting together.

*********************************************************
1# A boy is holding a 10 rupeese coin in his hand in front of his eyes, thus he is able to cover exactly the face of a person standing a distance away from the boy. The diameter of the 10 rupeese coin is 2.8 cm and the length from the top to the bottom of the person’s face is 22.4 cm. If the distance from the observer’s eye to the top of the coin is 75 cm, find the distance from the top of the 10 rupeese coin to the top of the person’s head.
2# Two poles of height 2 meters and 3 meters are 5 meters apart. The height of the point of intersection of the lines joining the top of each pole to the foot of the opposite pole is
3# Two poles of height 9 meter & 12 meter apart. The height of the point of intersection of the line joining the top of each pole to the foot of opposite pole is equal to?
4# Two poles of height 12 meter & 16 meter are at certain distance from each other. A thread from the top of first pole is tied to the foot of second and one more thread is tied from the top of other pole to the foot of first pole. Find the height of intersection point of two threads from the ground.
5# ABC is an isoceles triangle with AB =AC. AD is an angular bisector of angle A and its length is AD = 12 cm. LM and PQ are two perpendiculars on BC where LM = PQ. We have DQ = 6 cm and QC = 3 cm. Find the area of the shape ALMQP.
6# A factory is using an inclined conveyor belt to transport its products from Level 1 to Level 2 which is 3m above level 1 as shown by the figure below. The inclined conveyor is supported from one end to Level 1 and from the other end to a post located 8m away from Level 1 support point.The factory wants to extend its conveyor to reach a new Level 3 which is 9m above Level 1 while maintaining the inclination angle of the conveyor. Find the distance at which a new post is to be installed to support the conveyor at its new end at Level 2. Also, calculate the additional distance that the product has to travel to reach the new level.
7# Ram wants to to the office which is at O on the road PQ from his home which is at H on AB . AB || PQ. The road map between home and office as well as the distances known to Ram are as shown in the figure below. Find the shortest distance between ram’s home and office.
8# Nisha wants to measure the height of a building but she does not have the tools to do so. She noticed that there is a tree located in front of the building so she decided to use her smartness and the geometry knowledge that she got at school to measure the building height. She measured the distance between the tree and the building and found that it is 30m. She stood in front of the tree and started backing until she could see the top edge of the building from above the tree top. She marked her place and measured it from the tree. It was 5 m. Knowing that the tree height is 2.8m and Nisha’s eyes height is 1.6m. what is the height of the building she calculated.
