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.
True or false all isosceles triangles are also equilateral triangles?
False.
Is a triangle a small regular polygon?
A regular polygon is any polygon that has sides which are the same length and angles whose measures are equal. An equilateral triangle (also equiangular triangle) is a regular polygon. Other isosceles triangles (equilateral triangles are isosceles, but they are an exception) and scalene triangles are not regular polygons. A side note: Only in a triangle is a polygon regular solely if it is equilateral. (Since an equilateral triangle is equiangular as well). This is NOT always true in other polygons, like quadrilaterals, where it can be equilateral but not necessarily equiangular (a rhombus) or equiangular but not equilateral (a rectangle).
An equilateral triangle is a special case of an isosceles triangle?
true
Is it true that isosceles triangles have to have acute angles?
Yes
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
Is it true that all isosceles triangles can be equilateral triangles?
No
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.
True or false All equilateral triangles are also isosceles triangles?
True
True are false are all equilateral triangles are isosceles?
False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
True or false all isosceles triangles are also equilateral triangles?
False.
All equilateral triangles are acute and isosceles?
the answer is true, apex
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

If a triangle is isosceles then it is equalateral. what is the converse?
The converse is, "If a triangle is isosceles, then it is equilateral." Neither is true.
All equilateral triangles are similar true or false?
True as true can be.
