Given:

Four triangles A, B, C and D are given as below

Find:

we have to classify each triangle.

Step-by-step explanation:

Triangle A:

Since all the three sides of triangle A are of equal lengths.

Therefore, Triangle A is Equilateral.

Triangle B:

In triangle B, all the three angles are different, so all three sides are different.

Therefore, Triangle B is Scalene.

Triangle C:

Since, in triangle C, all the angles are equal, This means all the three sides are of equal lengths.

Therefore, Triangle C is Equilateral.

Triangle D:

In triangle D, two sides are of equal lengths.

Therefore, Triangle D is Isosceles.
