Geometry Practice Problems

Practice problems with full worked solutions for 20 shapes, graded from warm-up to stretch. Each page also generates unlimited new questions, so you can keep going until it sticks. Every answer comes from the same computationally verified function that powers the interactive explorers — free, no account, no sign-up.

How to use these

  1. Work it out on paper first. Reading a solution feels like learning and usually is not.
  2. Check, then read the working — the solution shows every substitution, so you can find the exact step where you went wrong rather than just the wrong total.
  3. Generate a fresh one when you get it right. Getting the same problem right twice proves less than getting two different ones right.
