@mcfate I had a duh moment. Then I turned it and was like it’s a straight line. I looked up and found the exterior angle method with a triangle
I kept wanting to call it 3π/4 radians, but that probably isn't helpful.
@vozoto Yes.
@vozoto has to be by definition, no?
@Beanc I had a duh moment.
@vozoto I have so very many of those.
@vozoto
That would indeed be a 135º angle.
Two ways you know: 90º plus 45º is 135º. Also, a flat line is 180º, and the complementary angle is correctly marked as 45º, 180º minus 45º is 135º.
