If it is an equilateral triangle then it is an isosceles triangle?
Let us recall the definition of an isosceles triangle. An isosceles triangle is a triangle with two equal or congruent sides. In this definition, it is not stated that it has exactly two equal sides. An equilateral triangle has three equal or congruent sides. If it has three equal sides, then it must have two equal sides. Therefore, an equilateral triangle is considered as an isosceles triangle. But, an isosceles triangle is not necessarily an equilateral triangle.
Why are scalene triangles and equilateral triangles different?
A scalene triangle has three unequal sides, an equilateral triangle has three equal sides. An isosceles triangle has two equal sides. Because with a scalene triangle only two sides are equal but with a equilateral triangle that would mean all sides are equal. (scalene = 2 sides & equilateral = all sides equal)
Is an equilateral triangle a isosceles triangle?
No. An equilateral triangle is where all three sides of the triangle are equal. An isosceles triangle is where only two of the sides are equal.
Is an isosceles triangle a equilateral triangle?
no because in an equilateral all sides are equal and an isosceles only two sides are equal
Is a isoceles triangle an equilateral triangle?
If it were, there would be no need to have two different names for it. An isosceles triangle has two equal sides. An equilateral triangle has all three sides equal.
