An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
This is not considered a "squashed square". This is considered a rhombus, a 4 sided parallelogram, with all four sides with equal lengths, and an area of d1d2/2, suits the Euler Characteristic just like a square F - E + V = 0 - 4 + 4 = 0, and is possibly a square if it has a single right angle.
