Question

4.
In Fig. 6.16, if x+y=w+z, then prove that AOB
is a line. please give my solution​

Answer 1

Answer:

first please mention the photos

I am 9th class that is why i understand!!!!

given : x+y=w+z

x +y = 180 ( equation 1)

w+z=180(equation 2)

adding eq 1 and eq 2

x+y+w+z=180+180

x+y+x+y=360. (given)

2(x+y)=360

x+y =360÷2

x+y=180

which means liner pair and if liner pair is happening then AOB is a line

Answer 2

hope it helps you out....
