No, those three examples cover all possible cases. If it is a triangle, then it is either acute, right, or obtuse.
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
A triangle can have a minimum of zero acute angles, which occurs in the case of a right triangle (which has one right angle) or an obtuse triangle (which has one obtuse angle). Therefore, it is possible for a triangle to have no acute angles at all.
obtuse
Yes . Triangle have right acute and obtuse angle except compelete angle.
A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
An acute triangle
right triangle
yes a isosceles triangle has a right,obtuse and acute angle.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
acute , obtuse obtuse or right angle
It is an acute angle.
