Question

answer please please ​

Answer 1

given OA parallel FC

so <1 = <2. (alternate interior angle ).................... (1)

again OB parallel FD

so <2 = <3 .............. (2)

from (1) & (2) <1 = <3

=》<AOB = <CFD

(Proved )

Answer 2

Step-by-step explanation:

Angle 3 and angle 2 are corresponding angles

Then, we know that corresponding angles on the side of transversal are equal

And angle 2 and angle 1 are corresponding angles

Then those are equal

So according to theorem of linear pair angles if an angle is equal to another two angles then those two angles are equal

So angle 3 is equal to angle 1

It's simple
