No. It has 3 angles of 60Â° each.

Only right triangles have right angles. An equilateral triangle though can't have a right angle because all the angles in any type of triangle must add up to 180 degrees. For each angle to be equilateral, they must be 60 degrees, showing that there is no angle at 90 degrees in an equilateral triangle, which would signify that it would be right.

A triangle in which one angle is equal to 90o is called a right triangle. A triangle in which all sides are equal (or) all the angles are equal to 60o is called an equilateral triangle. A triangle in which any two sides or any two angles are equal is called an isosceles triangle. A triangle in which all the sides or angles are different is called a scalene triangle.

No, that's not possible. Consider these facts: -- all three angles of any triangle always add up to 180 degrees -- all three angles in an equilateral triangle have to be the same size -- a right triangle has a right angle in it; a right angle is 90 degrees An equilateral right triangle would need three right angles in it, and they would add up to 270 degrees. As we said earlier: Impossible.

The sum of the interior angles of any triangle, including and equilateral triangle, is 180 degrees.

An equilateral triangle, which has 3 angles of 60o.

The sum of the interior angles of any triangle, including and equilateral triangle, is 180 degrees.

The sum of any triangle (including an equilateral one) is 180 degrees.

There are exactly 3 equal angles (of 60o) and three equal sides in any equilateral triangle.

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 equilateral triangle can be any size, by all of its angles must measure 60 degrees

No. All three angles of an equilateral triangle are equal (just like all three of the sides are). Since all three angles of any triangle have to add up to 180 degrees, each angle of the equilateral triangle has to be 60 degrees.
