Could you please elaborate the similarity property of ABC and DBC triangles in last golden triangle ? How are they similar ? Side common, one angle common, Min two angles are required na.
Raeez, the common side has nothing to do with it. The smaller triangle has 1 angle common (72 degrees) and one angle 36 because it is bisecting the other base angle of the large triangle (which is 72). So it is also a 36-72-72 triangle.

Not yet Shalini, after doing Geometry I had planned to put a few posts on that…
