Question

For each triangle, check all that apply. 60° Triangle A 60° Scalene Isosceles O Equilateral 60° 5 Triangle B 11 7 O Scalene O Isosceles O Equilateral 60 triangles by side... Triangle C 30° Scalene Isosceles O Equilateral Triangle D 8 O Scalene O Isosceles O Equilateral

Answer 1

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, in the triangle A, all the three angles are equal to 60 degree.Therefore, all three sides of triangle A are equal.

So, Triangle A is Equilateral.

Triangle B:

In triangle B all the three sides are different.

Therefore, triangle B is Scalene.

Triangle C:

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

Therefore, Triangle C is Scalene.

Triangle D:

In triangle D, two sides are equal.

Therefore, Triangle D is isosceles
