a 3 sided shape is a right angle triangle
an angle with a acute and right angle
The shape that has 1 acute angle, 1 obtuse angle, and 1 right angle is a scalene triangle. In a scalene triangle, all three angles are different, so it is possible for one angle to be acute (less than 90 degrees), one angle to be obtuse (greater than 90 degrees), and one angle to be a right angle (exactly 90 degrees). This unique combination of angles makes the scalene triangle a versatile geometric shape.
