There are two definitions of isosceles, one of which defines it as a triangle with exactly two equal sides, which excludes equilateral triangles. The other definition is a triangle with two or more equal sides and therefore is inclusive of equilateral triangles.

Is every equilateral triangle an isosceles triangle?
No, it is not.
Is every Isosceles Triangle an equilateral triangle?
NO but every Equilateral triangle is an Isosceles triangle. That is the difference . Isosceles triangles have only 2 sides the same length. Equilateral have ALL 3 sides the same length which means that they must have 2 sides the same length, so they are a very special case of an Isosceles triangle. That is why they have a special name - Equilateral meaning 'all sides equal'. The word lateral is a reference to the word length.
What is the contrapositive of the statement if it is an equilateral triangle then it is an isosceles triangle?
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
All isosceles triangles are also equilateral triangles?
No, all isosceles triangles are not equilateral triangles. An isosceles triangle is a triangle that has two sides of equal length. An equilateral triangle is a triangle that has all three sides of equal length. Therefore, it is possible for a triangle to be isosceles but not equilateral. For example, a triangle with sides of lengths 3, 3, and 4 is an isosceles triangle, but it is not an equilateral triangle because all its sides do not have the same length. On the other hand, all equilateral triangles are also isosceles triangles because they have two sides of equal length. My recommendation ʜᴛᴛᴘꜱ://ᴡᴡᴡ.ᴅɪɢɪꜱᴛᴏʀᴇ24.ᴄᴏᴍ/ʀᴇᴅɪʀ/372576/ꜱᴀɪᴋɪʀᴀɴ21ᴍ/
Are all isosceles triangles also equilateral triangles?
No, not at all, all isosceles triangles aren't equilateral since an equilateral triangle is a triangle with all of its sides equal, i.e. all sides of an equilateral triangle are equal, but in an isosceles triangle only two of its sides are equal.
Is every equilateral triangle an isosceles triangle?
No, it is not.
Is isosceles triangle also an equilateral triangle?
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
Is every isosceles triangle equiangular?
No but an equilateral triangle is equiangular
Can a equiangular triangle be an equilateral triangle?
Every equilateral triangle is equiangular, and every equiangular triangle is equilateral.
Are isosceles triangle sometimes an equilateral triangle?
Are isosceles triangle sometimes an equilateral triangle
Is every Isosceles Triangle an equilateral triangle?
NO but every Equilateral triangle is an Isosceles triangle. That is the difference . Isosceles triangles have only 2 sides the same length. Equilateral have ALL 3 sides the same length which means that they must have 2 sides the same length, so they are a very special case of an Isosceles triangle. That is why they have a special name - Equilateral meaning 'all sides equal'. The word lateral is a reference to the word length.
Is a right triangle an equilateral scalene or isosceles triangle?
It can be scalene or isosceles but not equilateral.
What is the contrapositive of the statement if it is an equilateral triangle then it is an isosceles triangle?
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
When is an equilateral trinagle isoceles?
If an isosceles triangle is one that has two equal sides,then I guess every equilateral trinagle is isosceles.
Are All equilateral triangles are isosceles.?
No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides
Which triangle are two sides and two angles equal?
Every isosceles triangle. An equilateral triangle is a special case of an isoceles triangle
Is an equilateral triangle equal to an isosceles triangle?
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
