Thread: Obtuse angles

Hello!

Im stuck at this question

How many obtuse angles can there be in an obtuse triangles??

Please help me!!

Sum of angles in triangle =? If one angle is obtuse say 95 degrees what can you say about the other two ?

Hello, julieta!

Did you make a sketch?

How many obtuse angles can there be in an obtuse triangle?

Suppose there could be two obtuse angles in a triangle.


The "triangle" might look like this:

Code:

     \                       /
      \                     /
       \                   /
        \                 /
         \ 92o       95o /
          *-------------*

Then where is the triangle?

OH okay!!

So if one angle is bigger than 90 degrees than there will not be any bigger angles in the triangle?! I got it!

Thanx soooo much! you really helped med out

Specifically, the sum of angles in any triangle is 180 degrees. If one angle is larger that 90 degrees, that leaves less than 90 degrees for the sum of the other two.
