Answer 1

Answer:

bisecting means making equal angles

Step-by-step explanation:

let aob=x

then eob=x/2

eoa=x/2

foe=180 so fob=180- x/2

similarly foa =180- x/2

hence proved

Answer 2

Step-by-step explanation:

given that AOB bisected by OF

it means : BOE = AOE ----1

now, BOE + FOB = 180 (Linea pair) ---- 2

similarly AOE + FOA = 180 ----3

Equating 2 and 3

BOE + FOB = AOE + FOA

FOB = FOA (cut BOE and AOE because of reason (1)

hence proved
