This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What representation and justification make a Grade 9 claim about distance, right triangles, and proof valid within its stated domain?
Getting the simulation ready…
- 1Build or change something
- 2Say what will happen, then run it
- 3Finish: say what you found
What counts as evidence- Reconcile the Grade 9 representations, explain the invariant relationship, and decide whether the boundary case supports or limits the conjecture.
- State the domain, assumption, or counterexample that prevents overgeneralizing the claim about distance, right triangles, and proof.
- linked representations
- valid computation
