Give credit to those who chose option 1 on question 11 on the June 2017 Geometry Regents

Question 11, "the rhombus question," has many students up in arms about the unfair trickiness of the June 2017 Geometry Regents. The question asked was: "which of three choices given would describe a parallelogram that could always be classified as a rhombus?" The third of three choices given was: "diagonals form four congruent isosceles right triangles."  A typical rhombus' diagonals form right, but not isosceles, triangles. The answer marked as correct by the board of regents though (option 4), includes this statement as being true. Here is why: a square is a type of rhombus, and a square's diagonals do form right isosceles triangles. Therefore, a shape that has that characteristic is a square, and thereby, also a rhombus. Although I was able to explain their rationale, we can clearly see that this was a sly and unnecessarily misleading question. Students who chose option 1 as their answer (that only the first 2 choices are correct) should be awarded credit for this question, in addition to those who chose option 4, which is the answer already given credit for by the state.
