"an equilateral triangle and
three isosceles triangles
together make a rhombus
what must the angles in the rhombus be?"
Do we really need to know that it's a rhombus? Could we just be told it's a parallelogram?

405: Triangles
How much of the description is necessary in order to find the solution?

I used consecutive angles, so the parallelogram information would be necessary. I'm not sure we need to know it's a rhombus to solve the problem, but it obviously has to *be* a rhombus (and we have to know it's a rhombus in order to construct the figure).
