Expert Answer:

The above figures can be classified according to its sides and angles in the following ways:-

(a)

Here, all sides are of different lengths.

Thus, it is a scalene triangle.

Also, it has a right angle in its interior.

Thus, it is a right-angled triangle.

(b)

Here, 2 sides are of equal lengths.

Thus, it is an isosceles triangle.

Also, it has an obtuse (>90o) angle in its interior.

Thus, it is an obtuse-angled triangle.
