3. APPLICATION OF CO-ORDINATE
GEOMETRY IN OUR DAILY LIFE
INTRODUCTION TO CO-ORDINATE GEOMETRY
coordinate is a number that determines the location of a
point along some line or curve.

4. Practical use of distance:
For construction of football ground, an architecture or engineer
firstly investigates the theory of forms and shapes of distance & geometry.
i.e. first picture of ground below.
C1 C4
In football ground, AB
must be equal to PQ for
any shot. Distance
A B P Q between C1 & C3 must
be equal to the distance
between C2 & C4. i.e.
C2 C3 C1C3=C2C4 and AB=PQ
C1 But in parallelogram
C4
shaped
ground, distance
between ball passing
from C1 to C3 & C2 to
C4 is unequal. i.e.
distance of C1C3 <
C2 C3
distance of C2C4

5. Position and use of angle(α):
It means, in our daily life , we walk and climb on different
stairs, roads or paths. Here, also we face the calculation of coordinate
geometry. Because of differences of slanted positions of different
paths, there forms a certain angle of observation. Thus, we feel easy &
difficult to walk or climb.
Difficult to climb up
Easy to climb up

6. Practical use of locus:
According to locus of a point, all the ropes joining at the balloon
must be equal. So, this helps balloon to take off easily. But if the ropes are
unequal, then the balloon will take off at a bend position.
x m. x m. x m.
P
All the ropes are equal from a If the ropes are unequal from a
point. point.

7. Direction of Movement:
In our daily life, we walk or run with respect to direction. We use
shortcut or easy to way to reach our destination for smooth work. For
5 e.g. this figure.

8. Distance and placement with respect to angle(α):
With these pictures, we can explain that a camera can catch all the
shapes & faces of people with respect to placement of horizontally and
vertically of pictures.

9. Use of sum of direction(Dn),distances(D), effort(E) & angle(α):
For the calculation of Dn, D, E & A; this can be observed in
different games such as Javelin thrown by an athletic players, etc.
Similarly, in below, basketball player uses this all of sums.

10. Conclusion:
Makes our work easy, simple and effortless.
Helpful in locating distance.
Helpful in locating point through locus.
Helpful in Construction works.
