General Information ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

GEOMETRY COORDINATE ,[object Object],[object Object],B (x 2 ,y 2 ) A (x 1 ,y 1 ) Line AB = (X 1 - X 2 ) 2 + (Y 1 - Y 2 ) 2

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Q (7,5) P (3,2)

GEOMETRY COORDINATE ,[object Object],[object Object],[object Object],B (x 2 ,y 2 ) A (x 1 ,y 1 ) Mid Point = x 1 + x 2 , y 1 + y 2 2 2 R

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],AB = x 1 + x 2 , y 1 + y 2 2 2 B (3,-1) A (5,7)

[object Object],GEOMETRY COORDINATE P (X 1 , Y 1 ) Q (X 2 , Y 2 ) n m R (a,b) a = nx 1 + mx 2 , b = ny 1 + my 2 m+n m+n

[object Object],[object Object],[object Object],[object Object],A (2,6) B (8,0) P 2 1 a = nx 1 + mx 2 , b = ny 1 + my 2 m+n m+n P = 1 x 2 + 2 x 8 , 1x6 + 2 x 0 2 + 1 2 + 1 = (6 , 2 ) So, coordinate P is (6,2).

Review DISTANCE Line AB = (X 1 - X 2 ) 2 + (Y 1 - Y 2 ) 2 RATIO m:n a = nx 1 + mx 2 , b = ny 1 + my 2 m+n m+n Mid Point = x 1 + x 2 , y 1 + y 2 2 2
