If the traveling right triangle is oriented the opposite way (Fig.

Therefore one got the same Angle Distortion Equations for a right triangle traveling with one of its legs along the motion direction.

He could note that both an isosceles

right triangle and a 30-60-90 degree triangle were triangles.

In the parallel small circle projection, corresponding partitioning lines in all right triangles within one face together construct a polygon (Figure 30).

This means that area equivalence is obtained when spherical right triangle T, and any shape contained in T, are mapped onto plane right triangle T with constant areal scale.

Exercise: Suppose that a right triangle has base a, side b and diagonal c.

1] determine the vertices of a right triangle with sides [x.

Noting that DE = G'B' = 1/3 (x + y) and that

right triangles G'EB' and JAB' are similar helps develop the desired result.
