Because the 3 angles in a right angle triangle add up to 180 degrees and if an obtuse angle was included then they would add up to over 189 degrees.
No because complementary angles add up to 90 degrees and an obtuse angle is greater than 90 degrees.
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
Two angles are complementary when they add up to exactly 90 degrees. An obtuse angle is by definition greater than 90 degrees. Therefore, an obtuse angle cannot have a complementary angle. So an obtuse angle and an acute angle are never complementary.
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
Yes, because the angles have to add up to 360º, at least one angle has to be obtuse.
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
Only if they add up to 180 degrees.

No because complementary angles add up to 90 degrees and an obtuse angle is greater than 90 degrees.
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
It has 1 obtuse angle and 2 acute angles that add up to 180 degrees
Two angles are complementary when they add up to exactly 90 degrees. An obtuse angle is by definition greater than 90 degrees. Therefore, an obtuse angle cannot have a complementary angle. So an obtuse angle and an acute angle are never complementary.
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
No-An equilateral triangle has equal angles, an obtuse angle is greater than 90. So, an equilateral triangle with an obtuse angle would have the three angles add up to a MINIMUM of 270.0000000000001, and a triangle's angles must add up to 180°.
No, an obtuse triangle can not have more than one obtuse angle. This is because all of the angles have to add up to 180 and the smallest obtuse angle you can have is 91 degrees. So 180-91=89. 89 degrees is the angle that you need to complete the triangle and it is an acute angle. Therefore, you can not have more than one obtuse angle in an obtuse triangle.
Any obtuse angle is greater than 90 but less than 180 degrees
