No, it can't be. 'Acute' means that all the angles are under ninety degrees; therefore, a ninety degree angle would make it impossible to have an acute triangle.

No. An acute triangle has to have three acute angles. A right triangle has to have one 90 degree angle.
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
No.
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
No the fact that it is right makes it impossible to be acute
