nurali · Answer

i think It has 3 sides.

hartnn · Answer

i didn't read the entire Q, but that figure is 'regular'
regular = all sides equal.

anonymous · Answer

so should i go with 3 sides or regular..?

anonymous · Answer

alright. so if the polygon is added to the triangle it would make it a rectangle. Should I then go with making it regular. Because I'm not sure if the four angles will be right angles..?

ok...i drew it on a paper, not necessarily regular, but it must have 3 sides, but it also has |dw:1366709443997:dw|exactly 4 right angles.
