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?

Suppose there could beobtuse angles in a triangle.*two*

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 (Rock) - March 16th 2011, 09:38 AMHallsofIvy
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.
