Question

if x+y=w+z, then prove that AoB is a line​

Answer 1

Step-by-step explanation:

$x + y = z + w \\ we \: can \: see \: that : \\ x + y + z + w = 360 \: \: \: (complete \: angle) \\ 2(x + y) = 360 \: \: \: \: (x + y = z + w) \\ x + y = \frac{360}{2} \\ x + y = 180 \\ therefore \: aob \: is \: a \: line$
