Question

co-ordinate zometry ki all formula​

Answer 1

Step-by-step explanation:

All Formulas of Coordinate Geometry

General Form of a Line Ax + By + C = 0

Slope Intercept Form of a Line y = mx + c

Point-Slope Form y − y1= m(x − x1)

The slope of a Line Using Coordinates m = Δy/Δx = (y2 − y1)/(x2 − x1)

The slope of a Line Using General Equation m = −(A/B)

Intercept-Intercept Form x/a + y/b = 1

Distance Formula |P1P2| = √[(x2 − x1)2 + (y2 − y1)2]

For Parallel Lines, m1 = m2

For Perpendicular Lines, m1m2 = -1

Midpoint Formula M (x, y) = [½(x1 + x2), ½(y1 + y2)]

Angle Formula tan θ = [(m1 – m2)/ 1 + m1m2]

Area of a Triangle Formula ½ |x1(y2−y3)+x2(y3–y1)+x3(y1–y2)|

Distance from a Point to a Line d = [|Ax0 + By0 + C| / √(A2 + B2)]
