Eight questions a sheet covering the eight polygons from triangle to decagon, and each question runs in one of two directions, chosen at random: name the polygon with this many sides, or say how many sides this polygon has. Both directions matter, because recognising a word is not the same as producing it - a student can answer "how many sides has a hexagon" from a half-memory and still be unable to name a seven-sided shape.
The four-sided shape is called a quadrilateral rather than a square or a rectangle, which is the distinction the page is quietly teaching: a quadrilateral is any four-sided polygon, and squares and rectangles are particular ones.
Triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon and decagon - three sides through ten.
Yes. Each question is drawn as either name-from-sides or sides-from-name, so a sheet practises recognising the word and producing it.
A square is one kind of quadrilateral, not the name for four sides. Every name on the sheet describes a side count and nothing else, which is what keeps the set consistent from three to ten.
No. These questions have no angle in them, so the setting has nothing to act on - it is left unset here for that reason.
