What’s on the Quadrilaterals poster
A 6-row table: Shape · Sides · Angles.
A quadrilateral is any closed shape with four straight sides. These are the named ones.
- Square — 4 equal, 2 parallel pairs — 4 right angles
- Rectangle — opposite sides equal — 4 right angles
- Rhombus — 4 equal sides — opposite angles equal
- Parallelogram — 2 parallel pairs — opposite angles equal
- Trapezium — exactly 1 parallel pair — no rule
- Kite — 2 pairs of equal neighbours — 1 pair of equal angles
Every square is a rectangle and a rhombus. Not every rectangle is a square.

- Who is the Quadrilaterals poster for?
- Quadrilaterals is filed under 3rd Grade (ages 8–9), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Quadrilaterals poster?
- Draw each one and count the parallel sides. That is what separates them. A wall chart earns its place by being glanceable from where the work is happening, so Quadrilaterals belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Quadrilaterals?
- Right, Acute, Obtuse, Area and Perimeter and Which Operation? sit alongside Quadrilaterals in the 3rd Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Right, Acute, ObtuseArea and PerimeterWhich Operation?
- Is the Quadrilaterals poster free to download and print?
- Yes. Quadrilaterals downloads as a free PDF with no account, no email and no watermark, like everything else in the 3rd Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Quadrilaterals poster print at?
- Quadrilaterals is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Quadrilaterals loses nothing.Printing guide
