Best Answer

It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.

Yes . Triangle have right acute and obtuse angle except compelete angle.

yes a isosceles triangle has a right,obtuse and acute angle.

This is not possible. If a triangle is a Right angled triangle then the sum of the two angles which are not right will be = 90 [Angle Sum Property] That's why you see.

If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.

An obtuse triangle has one angle greater than 90 degrees.

If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.

No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees

-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .

If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute

Yes . Triangle have right acute and obtuse angle except compelete angle.

A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles

A triangle can never include a right angle and an obtuse angle together in it.

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)

because if it is obtuse, there is no right angle. each corner has to be over 90 degrees (a right angle) to be an obtuse triangle.

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 right triangle has a 90 degree angle, and an obtuse triangle has an angle greater than 90 degrees

No, it isn't possible for a right triangle to have an obtuse angle.
