Can a obtuse angle have a complement?
No because complementary angles add up to 90 degrees and an obtuse angle is greater than 90 degrees.
Explain Why can't a right triangle can't have an obtuse angle in it?
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.
Is an acute angle and an obtuse angle sometimes always or never complementary?
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.
What statement is always true about an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
Can an obtuse triangle have more than one obtuse angle?
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.
