Question

How can I prove that a 123° angle isn't an obtuse

Answer 1

Obtuse means larger than 90 degrees, so 123 degrees is obtuse

Answer 2

basically you can't prove this :v is false

Answer 3

I know that. But Im Doing converses and I need to prove that a 123° angle isn't a obtuse

Answer 4

Have you answered it as obtuse in your test ?

Answer 5

The converse of the question I just asked

Answer 6

@ganeshie8 remember we can't help with tests

Answer 7

Converse or inverse of a statement need not be true...
what exactly is the complete problem ?

Answer 8

the converse of the statement is true but the statement itself is false

Answer 9

But I need to prove that it's not true.. Making if false is what I'm suppose to be doing and this is not a test I need help with homework this is homework

Answer 10

hmm, can you share a screenshot of the entire problem?

Answer 11

How

Answer 12

Is the question:
"Prove 123 deg angle is obtuse"?

Answer 13

ya i think its a proof by contradiction

Answer 14

More than 90 degrees = Obtuse angle
90 degrees = Right angle
Less then 90 degrees = acute angle
180 degrees = straight angle

There is no way to prove that a 123 degree angle is not an obtuse, because it is and always will be an obtuse angle.
