Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not 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
How many sides does a obtuse isosceles triangle have?
By definition, all triangles have 3 sides.
Are All equilateral triangles are isosceles.?
No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides
What can isosceles triangles be used in?
Isosceles triangles can be used in domes
Does an isosceles triangle have two sides of equal length?
The definition of an isosceles triangle is a triangle with at least two sides of equal length, which means it also has two angles of equal measurement. As such, equilateral triangles; triangles in which all sides and angles are congruent (Of the same size) are also considered to be isosceles triangles.
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.
Are all isosceles triangles right triangles?
No, only one is and it is known as a 'right isosceles triangle'. By definition an isosceles triangle has two equal sides and two equal angles. If those two equal angles are 45o then the third angle must be 90o.
Are all right triangles an isosceles triangles?
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
What are isosceles triangels?
Isosceles triangles are triangles in which two of the three sides have different lengths.
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.
