## Lime 3 years ago More angles! Are 3 and 4 complementary?

do you know the definition of complementary angles?

Poor drawing, but yes.

Complementary angles are angles whose sum is 90 degrees.

8. completeidiot

complementary angles are just angles that add up to 90 degrees so what is the sum of angles 3 and 4?

9. Lime

The sum of angles 3 and 4 are/is 30 degrees and 60 degrees = 90 degrees?

10. completeidiot

|dw:1346202538368:dw| how is this 30 degrees, its way obviously an obtuse angle

11. completeidiot

also understand that straight lines|dw:1346202606723:dw| are equal to 180 degrees

I meant angle 4 was about 30 degrees.

14. completeidiot

ok then how is angle 3 60 degrees?

15. Lime

Angle 3 is more than that. About 150?

16. completeidiot

ok then 30+150 = 90???

17. completeidiot

complementary angles are the sum of 2 angles that equal 90 degrees but 30 +150 does not equal 90 degrees So are your 2 angles complementary???

18. Lime

No.

19. completeidiot

good job

20. completeidiot

angles 3 and 4 would be considered supplementary angles because the sum is equal to 180 degrees

21. Lime

Got it.
