Right Triangles (Posted on 2010-01-22) Difficulty: 2 of 5
Triangle ABC is right-angled at C, a = |BC|, b = |CA|, with a < b.
Squares ABDE, BCFG, and CAHI are erected externally to triangle ABC.
Lines HE and DG intersect at P, lines DG and FI intersect at Q, and lines FI and HE intersect at R.

If triangle PQR is right-angled, determine the value of b/a.

Why not a note about the angle at P and R?
