### 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

### Is an isosceles triangle sometimes an equilateral triangle?

sometimes, but not always

### Are isosceles triangle sometimes an equilateral triangle?

Are isosceles triangle sometimes an equilateral triangle

### Is an equilateral triangle always or sometimes called an isosceles?

If you can only prove two sides of an apparently equilateral triangle to be congruent then you have to use isosceles.

### Can you show me a triangle with only one line of symmetry?

An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:

### 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.

### Are All equilateral triangles are isosceles.?

No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides

### Are equilateral triangle is always an isosceles triangle?

No because they are different types of triangles inasmuch that an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides

### 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 an isosceles triangle sometimes always or never equilateral?

An isosceles triangle is one that has two sides of the same length and one side different An equilateral triangle is one that has all of its sides of equal length. All of the angles on an equilateral triangle are 60 degrees. A triangle with two sides 4cm and one side 100m would be an isosceles. But an equilateral triangle has all of the sides exactly the same so therefore an isosceles triangle can never ever be an equilateral triangle

### A isosceles triangle is a special type of equilateral triangle?

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.
