Question

The angles of a triangle measure ${40}^o$, ${110}^o$and ${30}^o$. Such a triangle is called a/an _________.

Answer 1

If an angle of a triangle is obtuse (more than ${90}^o$ ), the triangle is called an obtuse angled triangle.

Since the measure of one of the angles of the given triangle is ${110}^o$, it is an obtuse angled triangle
