Mathematics rules of H.S.C(geomettry) #### Rules of Geomettry:

There are 5 chapter in higher secondary geometry.
1. Coordinates.
2. Straight line.
3. Circle.
4. Conics.
5. Vector.
1.Coordinates.

There are 3 types of coordinates:

1. Rectangular coordinates.
2. Polar coordinates.
3. Kertatio coordinates.
For polar coordinates:  For kertatio coordinates:  Find distance between 2 points.

Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is: Divider rule: 2 types divide rule:

1.Inner divide.

Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:  2.Outer divide.

Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:  Find out area of a triangle: Straight line.

Equation of X-axis,y=0

Equation of Y-axis,x=0

Equation of one point movement straight line: Equation of two point movement straight line: Circle.

If center is main point and radius is a then equation of this circle is: If center is (h,k) and radius is a then equation of this circle is: By expanding it we found: It's center is(-g,-f) and radius, Conics.

Equation of parabola: Equation of ellipse: Equation of hyperbola: At first you can print it and then hang it infront of your table.

After that you can get help form it.
