Question

All of the triangles above are _____ triangles.

Answer 1

They are all Isosceles 

Answer 2

All of the triangles above are isosceles triangles.

Explanation:

From the figure, it can be seen that there are three triangles.

For first triangle, two of the sides of this triangle are equal in measure that is 3 units, therefore the given triangle is an isosceles triangle because in isosceles triangle, two of the three sides of given triangle are equal.

For second triangle, two of the sides of this triangle are equal in measure that is 33 units, therefore the given triangle is an isosceles triangle.

For third triangle, two of the sides of this triangle are equal in measure that is 4 units, therefore the given triangle is an isosceles triangle.

Thus, All of the triangles above are isosceles triangles.
