What’s on the Distance and Midpoint poster
The rule, 4 worked examples.
- Distance uses Pythagoras on the horizontal and vertical gaps. Midpoint is simply the…
- d = √[(x₂−x₁)² + (y₂−y₁)²]
- (1,2) to (4,6) = d = 5
- Midpoint of (1,2),(4,6) = (2.5, 4)
- Why it works = it is a right triangle
- Order of subtraction = does not matter
Distance is a single number. Midpoint is a point, so it needs two coordinates.

- Who is the Distance and Midpoint poster for?
- Distance and Midpoint is filed under 8th Grade (ages 13–14), 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 Distance and Midpoint poster?
- Distance is a subtraction then a root. Midpoint is an average. Do not mix them up. A wall chart earns its place by being glanceable from where the work is happening, so Distance and Midpoint belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Distance and Midpoint?
- Angles and Parallel Lines, Exponent & Radical Rules and Three Forms of a Line sit alongside Distance and Midpoint in the 8th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Angles and Parallel LinesExponent & Radical RulesThree Forms of a Line
- Is the Distance and Midpoint poster free to download and print?
- Yes. Distance and Midpoint downloads as a free PDF with no account, no email and no watermark, like everything else in the 8th 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 Distance and Midpoint poster print at?
- Distance and Midpoint 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 Distance and Midpoint loses nothing.Printing guide
