Question
Equilateral triangle is also ______.
- a right angled triangle
- an isosceles triangle
- A scalene triangle
Hint:
The isosceles triangles is a triangle in which any two sides are equal.
Here, isosceles triangles are the super set of equilateral triangles.
The correct answer is: an isosceles triangle
ANS :- Option B
Explanation :-
Equilateral triangles have all three sides equal .To be an isosceles we only need 2 here we have 3 .So , the equilateral triangle is also an isosceles triangle.

Note:
Instead of adding 2 on both sides, we can also understand the concept by taking -2 of the right hand side on the left hand side and then the sign changes to + 2 . Similarly, instead of subtracting both sides by , we can understand it by saying that we take + x from the left hand side to the right hand side, and here it becomes - x .
Thus, addition becomes subtraction and vice-versa when taken from left hand side to right hand side or the opposite way; and multiplication becomes division and vice-versa. Be careful, 0 is never taken in the denominator.
