Step-by-step explanation:

Given Classify a triangle with sides measuring 2 cm, 5 cm and 9 cm and one angle 128˚ 1 point Scalene and Obtuse angled triangle Scalene and Right angled triangle Scalene and acute angled triangle Scalene and reflex angled triangle

• We have triangle with all sides equal are called equilateral triangle, two sides are equal are called isosceles triangle and if no sides are equal then it is a scalene triangle.
• Here the sides are measuring 2 cm, 5 cm and 9 cm and no sides are equal and hence it will be a scalene triangle.
• Also the angle is 128 degree.  
• Angle which is more than 90 degree but less than 180 degree is obtuse angle.

So scalene triangle and obtuse angle triangle holds good.
