I think it might be a reflex angle

snowflake0531:

2 angles that add up to 90 degree are called complementary angles

do you know what a reflex angle is? e.e

snowflake0531:

*degrees

hhanan:

A angle that is 190 degrees?

snowflake0531:

anyways, i actually meant it as a rhetorical question, that it isn't a reflex angle lol

hhanan:

a right angle

darkknight:

snowflake, describe hhanan why it isn't a reflex angle looking at the picture, in case they don't understand

snowflake0531:

Well, the two angles added up are 90 degrees clearly meaning each of the angles are smaller than 90 degrees and for a reflex angle to be a reflex angle it has to be at least 180 degrees... which it isn't?

hhanan:

an acute angle

snowflake0531:

Yes it's an acute angle BUT it also complements the other angle to 90 degrees

snowflake0531:

And if the question wanted you to state that it's acute, it wouldn't have drawn all that

hhanan:

so the right angle

snowflake0531:

? just write that it's a complementary angle

darkknight:

a complementary angle is angles that add up to 90 degrees, isn't this a right angle + some acute angle?

darkknight:

the right angle and the acute angle does not add up to 90 degrees, so how it is complementary?
