Jumlah dua sudut yang berpelurus adalah . Diketahui , maka : Sehingga, : Jadi, dan .

Jumlah dua sudut yang berpelurus adalah 180 degree .

Diketahui sudut space straight A equals 2 over 5 space sudut space straight B , maka table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight m end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank angle end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight B end table :

$table attributes columnalign right center left columnspacing 0px end attributes row cell angle straight A plus angle straight B end cell equals cell 180 degree end cell row cell 2 over 5 angle straight B plus angle straight B end cell equals cell 180 degree end cell row cell open parentheses 2 over 5 plus 1 close parentheses angle straight B end cell equals cell 180 degree end cell row cell fraction numerator 2 plus 7 over denominator 5 end fraction angle straight B end cell equals cell 180 degree end cell row cell 9 over 5 angle straight B end cell equals cell 180 degree end cell row cell angle straight B end cell equals cell 180 degree times 5 over 9 end cell row cell angle straight B end cell equals cell 100 degree end cell row cell straight m angle straight B end cell equals cell 100 degree end cell end table$

Sehingga, table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight m end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank angle end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight A end table :

table attributes columnalign right center left columnspacing 0px end attributes row cell angle straight A end cell equals cell 2 over 5 angle straight B end cell row cell angle straight A end cell equals cell 2 over 5 times 100 degree end cell row cell angle straight A end cell equals cell 40 degree end cell row cell straight m angle straight A end cell equals cell 40 degree end cell end table
