Notice it always remains an equiangular triangle. The angles A,B and C always remain equal in measure. An equiangular triangle is a triangle where all three interior angles are equal in measure. Because the interior angles of any triangle always add up to 180Â°, each angle is always a third of that, or 60Â° The sides of an equiangular triangle are all the same length (congruent), and so an equiangular triangle is really the same thing as an equilateral triangle. See Equilateral Triangles. Properties
Radians measures the angle in terms of the length of the arc that will be subtended on the circumference of a circle of one (dimensionless) unit. It can be found by the equation: 2*pi*(degrees/360) Grads, however, divides the right angle into 100 parts instead of 90. It is often used in artillary measurements as it is often simpler to world of a base-10 than a base-9. Gradians To Degrees. radians are used to evaluate things in polar.
