which types of angles can an obtuse triangle have? a right angle an obtuse angle two vertical angles or two acute angles oh and it has to be 2 of them

OpenStudy (midhun.madhu1987):

An Obtuse triangle is a triangle in which only one angle is greater than 90 (Obtuse angle) and the other 2 angles must be less than 90 (Acute Angle).

OpenStudy (anonymous):

okay a triangle equals 180 so, wouldn't it be a right angle which is 90 with 2 acute since they will equal an obtuse angle

OpenStudy (midhun.madhu1987):

That would be only a Right triangle. Here it is Obtuse triangle...

OpenStudy (anonymous):

but, a right triangle plus 2 acute angles would be obtuse

OpenStudy (midhun.madhu1987):

Nope.. for a triangle to be an obtuse triangle, one angle must me greater than 90
