That's because it is possible to find two sides that have the same length.
Are isosceles triangle sometimes an equilateral triangle
It can be scalene or isosceles but not equilateral.
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
If you can only prove two sides of an apparently equilateral triangle to be congruent then you have to use isosceles.
No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
An equilateral triangle has all sides measuring the same and an isosceles triangle has 2 sides congruent, so they are not the same. Every equilateral triangle is also an isosceles triangle, but not every isosceles triangle is an equilateral triangle. Isosceles = at least two equal sides Equilateral = three equal sides
Not ... exactly. It would be closer to accurate to say that an equilateral triangle is a special case of the isosceles triangle.All equilateral triangles are (also) isosceles; but most isosceles triangles are not equilateral.
Isosceles has 2 equal sides, but an equilateral triangle, all of its sides are equal.
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.
No
No.
