Question

hi how to solve this​

Answer 1

Answer:

in the figure OE bisect angle AOD

SO

ANGLE AOE(X)=ANGLE EOD(X) CONSIDE THE ONE ANGLE AS X

IN the figure oc bisect DOC

ANGLE DOC (Y)= ANGLE COB (Y). CONSIDE THE ONE ANGLE AS Y

IN the figure OE is |. to of

so

angle EOC (ANGLE X +ANGLE Y)= 90 DEGREE

(THE ANGLE IN A LINE = 180 )

SO

THE QUESTION IS TO PROVE THAT AB IS A STRIGHT LINE

THE TOTAL ANGLE =X+X+Y+Y= 180 DEGREE. (X+Y=90)

SO AB IS A STRIGHT LINE
