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.
Each of the 3 angles in an equilateral triangle are 60 degrees.

A right angle triangle can only have 1 right angle of 90 degrees and its 3 interior angles add up to 180 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.
Each of the 3 angles in an equilateral triangle are 60 degrees.
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 sum of the internal angles of a triangle is 180 degrees. If you know the size of the angles at the base of an isosceles triangle, the final angle can be found by subtracting the size of the two known angles from 180.
You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
