Is every equilateral triangle isosceles?
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.
All equilateral triangles are also isosceles triangles?
True or False, depending on your definition of isosceles triangles!Actually, whether your answer is true or false depends upon your definition of an isosceles triangle. Some mathematicians define an isosceles triangle as one with at least two sides, while others define an isosceles triangle as one with exactly two sides. The latter definition is the more generally accepted one. Since an equilateral triangle has three, not exactly two congruent sides, people using the second definition of isosceles triangles would say that the statement is false, not true.False because an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides
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.
Does an Isosceles have two equal sides?
Yes. Isosceles triangles have two identical sides and angles. They are also longer than the third side.All triangles have three sides. Isosceles triangles have two sides of the same length.
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Are all equilateral triangles isosceles true or false?
False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
Can equilateral triangles be isosceles triangles?
no. Equilateral triangles have all equal sides. Isoceles triangles only have 2 congruent sides. Isosceles triangles have 2 equal sides.
How are equilateral triangles and isosceles triangles different?
Equilateral triangles have 3 equal sides whereas isosceles triangles have only 2 equal sides
What is the difference between an isosceles and an scaline triangle?
An equilateral triangle is a triangle where all of the sides are of equal length. An isosceles triangle is a triangle that has only two sides that are of equal length.
Do all isosceles triangles have 3 equal sides?
Only an equilateral triangles have 3 equal sides whereas an isosceles triangle has only 2 equal sides.
Do isosceles triangles have all equal sides?
Some people classify isosceles triangles as having at least two equal sides, while other say that they must have exactly two equal sides. So, depending on your definition, some isosceles triangles may have all equal sides, but equilateral triangles always have three equal sides.
Do icosceles triangles have all 3 sides equal?
No. Isosceles triangles have two sides of equal length.

Yes. Isosceles triangles have two identical sides and angles. They are also longer than the third side.All triangles have three sides. Isosceles triangles have two sides of the same length.
Can all isosceles triangles equilateral?
No because although both triangles have 3 sides an isosceles triangle has 2 equal sides whereas an equilateral triangle has 3 equal sides.
