Answer:
@BOY+@AOY=180 BEING LINEAR PAIR--------(1)
AGAIN
since ON is the bisector then 1/2of @BOY=@NOY
SIMILLARLY 1/2 of @AOY= @MOY
from (1) we have
1/2(@BOY+@AOY)=1/2of 180
=>1/2of @BOY+1/2of@AOY=90
=>@NOY+@MOY=90
=>@MON=90°
hence MO and ON are perpendicular to each other
note**** @ represents angle
