No
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
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.
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.
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)
True
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)
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 or an isosceles triangle if the 2 acute angles are equal in size
cannot because a triangle has to have 180 degrees i.e. obtuse angled triangle has one obtuse angle acute angled triangle has three acute angles
-- 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 .
Every triangle must have at least two acute angles. The third one can be acute, right (90 degrees), or obtuse.
