Size or internal angles?

True. In any triangle, the longest side is always opposite the largest angle; the shortest side is always opposite the shortest angle; and the middle length side is always opposite the middle size angle. In an isosceles triangle, there is no middle length side; and the two sides of equal length are opposite the angles of equal size. In an equilateral triangle, all sides are the same length, as are all the angles.

In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.

An Isosceles right triangle. If the length of either of the two sides is N then the hypotenuse is N times the square root of 2. an isosceles right triangle can not be an equilateral triangle since the hypotenuse can not be the same size as the other two sides..

The internal angles of a triangle add up to 180 degrees so in an equilateral triangel each internal angle must be 60 degrees, as 3 x 60 = 180.

The size of the 3 interior angles of an equilateral triangle each measure 60 degrees

The sum of the internal angles in a triangle is equal to 180 degrees. An equiangular triangle, otherwise known as an equilateral triangle, has three angles of the same length, and three angles of the same size. The size of each angle is 180 / 3 = 60 degrees.
