Diketahui , dan . Titik pada sehingga , maka: Sehingga: Jadi, adalah satuan panjang

Diketahui A left parenthesis 0 comma space 1 comma space 5 right parenthesisB left parenthesis 0 comma space minus 4 comma space 5 right parenthesis dan C left parenthesis 3 comma space minus 1 comma space minus 4 right parenthesis. Titik P pada A B sehingga A P space colon space A B equals 2 space colon space 5, maka:

table attributes columnalign right center left columnspacing 0px end attributes row cell A P space colon space A B end cell equals cell 2 space colon space 5 end cell row cell fraction numerator P minus A over denominator B minus A end fraction end cell equals cell 2 over 5 end cell row cell 5 open parentheses P minus A close parentheses end cell equals cell 2 left parenthesis B minus A right parenthesis end cell row cell 5 P minus 5 A end cell equals cell 2 B minus 2 A end cell row cell 5 P end cell equals cell 2 B minus 2 A plus 5 A end cell row cell 5 P end cell equals cell 2 B plus 3 A end cell row P equals cell fraction numerator 2 B plus 3 A over denominator 5 end fraction end cell row P equals cell fraction numerator 2 left parenthesis 0 comma space minus 4 comma space 5 right parenthesis plus 3 left parenthesis 0 comma space 1 comma space 5 right parenthesis over denominator 5 end fraction end cell row P equals cell fraction numerator left parenthesis 0 comma space minus 8 comma space 10 right parenthesis plus left parenthesis 0 comma space 3 comma space 15 right parenthesis over denominator 5 end fraction end cell row P equals cell fraction numerator left parenthesis 0 comma space minus 5 comma space 25 right parenthesis over denominator 5 end fraction end cell row P equals cell left parenthesis 0 comma space minus 1 comma space 5 right parenthesis end cell end table 

Sehingga:

Jadi, open vertical bar stack P C with rightwards arrow on top close vertical bar adalah table attributes columnalign right center left columnspacing 0px end attributes row blank blank 3 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell square root of 10 end cell end table satuan panjang
