The term isometric comes from the Greek for equal measure, reflecting that the scale along each axis of the projection is the same (unlike some other forms of graphical projection).
Isosceles Trapezoid An isosceles trapezoid (called an isosceles trapezium by the British; Bronshtein and Semendyayev 1997, p. 174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. From the Pythagorean theorem, h=sqrt(c^2-1/4(b-a)^2), (1) so A = 1/2(a+b)h (2) = 1/2(a+b)sqrt(c^2-1/4(b-a)^2).
