right triangle and equilateral triangle both have 3 sides
One more because an equilateral triangle has 3 equal sides whereas a right isosceles triangle has only 2 equal sides.

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.
It is called and equilateral triangle. You can find more information about equilateral polygons here: http://www.answers.com/equilateral
No congruent sides is a scalene, two congruent sides is an isosceles triangle, three is an equilateral.
An equilateral triangles.
An equilateral pentagon.
No.
An isosceles triangle has two congruent sides, andAn equilateral triangle is a special isosceles triangle in which all three sides are congruent.Therefore, all equilateral triangles are isosceles by definition.See this link for more: http://library.thinkquest.org/20991/geo/ietri.htmlFor easier words yes because iscosceles has only has 2 equal sides and equilateral triangles sides are equal and iscoseles has two so yea....no it can't because equilateral means all sides are the same and a isosceles triangle means only 2 sides are the same
This is called an equilateral triangle.A triangle that has all sides equal is called "equilateral."Because all the sides are equal, all of the angles will be equal as well and may also be considered "equiangular." However, "equilateral" is the more common term.
No, never. There's more than one way to get at it: -- The angles of an equilateral triangle are all equal. Since the interior angles of any triangle always add up to 180 degrees, the angles of an equilateral triangle are each 60 degrees. There's no right angle. -- A right triangle is a triangle with an interior right angle. An equilateral triangle has three equal angles. If it were a right triangle, each angle would be a right angle. Then: -- the three interior angles would add up to 270 degrees, which is impossible in a triangle; and -- two sides would be parallel to each other, they would never meet, and there could be no triangle. -- The sides of a right triangle satisfy the Pythagorean equation: A2 + B2 = C2. If all three sides were equal, then you'd have (two times the square of a number) equal to (the square of the same number), which isn't possible. -- Remember that the 'hypotenuse' of a right triangle is the longest side. But an equilateral triangle can't have a 'longest' side.NOA right triangle always has a 90 degree angle and an equilateral triangle always has three 60 degree angles, so no.
An isosceles (2 equal sides), equilateral (3).
