The sum is greater than 90 degrees and less than 270 degrees.
No, because if there is on obtuse angle the triangle will always be obtuse.
Of course not! There are obtuse and acute triangles.
no
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
No, the complement of an acute angle is not obtuse. An acute angle is defined as an angle that is less than 90 degrees, so its complement, which is found by subtracting the acute angle from 90 degrees, will always be greater than 0 degrees and less than 90 degrees, making it also an acute angle. Therefore, the complement of an acute angle is always acute, not obtuse.
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.

Always 2 acute angels, and the third an be acute, right, or obtuse.

No :) Because one angle of the triangle is always acute and so the exterior has to be obtuse.
Yes it dose.
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
