Question

Name each of the following triangles in two different ways: (you may judge the nature of the angle by observation)

Answer 1

Classification of triangles:

A scalene triangle is a triangle in which all three sides are of different lengths, and all three angles are of different measures.

A triangle whose anyone of the angles is more than $90°$.then, it is called an obtuse-angled triangle.

From the given figure of the triangle, It is observed that all three sides are unequal and one angle of the triangle is more than $90°$.

Hence, the given triangle is an obtuse-angled and scalene triangle.
