The 90 degree angle is cut in two parts...Obviously. The definition of Complementary is something that equals 90 degrees. so due to the definition of complementary...

HarleyQuinn112:

1. I love your username 2. they are complementary?

slipknot3066:

Yes they are. And thanks lol

HarleyQuinn112:

thats what i said and my teacher said that it was wrong :( and your welcome lol

slipknot3066:

cutting a 90 degree angle into two makes two 45 degree angles....t.f

HarleyQuinn112:

well at least you agree with me lol

slipknot3066:

Perhaps the question isn't asking for "is it complementary" perhaps it is asking for "with the given photo, can you tell if it is complementary?" maybe.

Vocaloid:

it is not stated that the angle is 90 degrees so you cannot prove they are complementary
