No it is impossible a triangle can have: 3 acute angles 1 right and 2 acute angles 1 obtuse and 2 acute angles
right
It is a right angle
NO!!! All four angles are right-angles (90 degrees) The word 'rectangle' means -right-angled quadrilateral.
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
