The exterior angle theorem is Proposition 1.16 in Euclid's Elements, which states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles. This is a fundamental result in absolute geometry because its proof does not depend upon the parallel postulate.

I said to say yes or no.
no
I think it is yes.
the answer is no becauseinterior angle + exterior angle of triangle = 180° (linear pair)
⇒ x + y = 180
if x = 180 (given)
180 + y = 180
y = 180 - 180 = 0
It can't be so..
