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


Can an isosceles triangle be equilateral?

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


How are isosceles triangle and equilateral the same?

one way is the both are in the triangle group and they both are a type of triangle


What is one way scalene triangle equilateral triangle and isosceles are the same?

they all have three sides


What kind of a triangle has 3 equal sides?

Equilateral triangle. Note the "equal" in "equilateral". Isosceles triangles have two sides that are the same and one is not. SOS in "isosceles" help me remember this.


How many lines of symmetry are there in a triangle?

In an equilateral triangle: 3 In an isosceles triangle: 1 In a scalene triangle: 0


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 equilateral triangle always an isosceles triangle?

If an isosceles triangle is defined as one which has two sides (or angles) equal, then YES. But if an isosceles triangle is defined as one which has two sides (or angles) equal, and the third side (angle) different, then NO.


Can an isoceles triangle be equilateral?

-- Some mathematicians define an 'isosceles' triangle as one with at least twoequal sides. They would say that equilateral triangles are isosceles.-- Other mathematicians define an 'isosceles' triangle as one with exactly twoequal sides. They would say that equilateral triangles are not isosceles.


What is the symmetry type of an isosceles non equilateral triangle?

An isosceles triangle has two equal sides and one line of symmetry


Triangle with one axis of symmetry?

Any isosceles triangle which is not also an equilateral triangle. An equilateral triangle would have three.


What equilateral triangles are isosceles?

No.
