In the question where another regular polygon shape exactly fitted onto point B, most people wrote Equilateral Triangle but some others including myself wrote Rhombus, since Rhombus is also a regular sided polygon. Is it correct? As it's vertex does fit onto point B. Or have I lost that 1 mark? :p

It was isosceles triangle.

IT WAS ISOSCELES CONFIRM, because two sides were equal in the space and the base was shorter, so only isosceles triangle could fit, and nothing else.

You guys are all wrong ...

The only correct answer was triangle .. no matter what ..

IT WAS A REGULAR polygon.

remember something? in a regular polygon all angles are equal. so that triangle wasn't isosceles there's that. but one will get the mark for mentioning triangle regardless. Whoever wrote Triangle only or Equilateral triangle will get full marks.

and as far as rhombus goes .. that's completely incorrect.

It was which regular would fit in between two of those 12-sided polygons ..

one angle was 150 for them ..

so 360 - 150 - 150 = 60 Degrees .. therefore whatever regular polygon was there has to have a 60 degree interior angle.

(n-2)*180/n = 60
180n-360=60n
120n=360
n=3

now tell me which is a polygon with ONLY 3 equal 60 degree angles .. does rhombus has ONLY 3 angles?

Read my explanation above .. that's how one had to prove it.

You're telling me that it was just triangle and not isosceles triangle ?

Yes. More specifically an Equilateral Triangle.

As it was mentioned in the question that its an regular polygon, writing triangle was enough.

I wrote equilateral triangle .. but then cut equilateral part, and left triangle over there.

one can lose 36 marks for an A if i am not wrong, right? but your target should be to go not below 27 .. so even if the percentile does go high .. you still get an A ;)
