Live construction

Prepare the plane

Begin with an equal-scale coordinate system.

One square represents one unit in both directions, so length and perpendicularity remain geometrically honest.

As Q moves, what path will P trace?

Teacher cue

Ask: What must be preserved if this diagram is to support geometric reasoning?
Look for: Students noticing that equal units on both axes are essential.
Then: Advance only after the coordinate system has been checked.
