Every construction,
built before your eyes.
Then built by you.
All fifteen Junior Cycle geometry constructions as living drawings: watch each compass arc and ruled line land in order, drag the givens to see the method re-derive itself, then switch to Your turn and earn the stamp.
Right tools only
Some constructions permit only compass + straight edge. Reaching for a ruler or protractor on those loses marks — the palette below locks what's forbidden, and tells you why.
Never rub out your arcs
Construction marks are the evidence of your method. Examiners award marks for them. The eraser stays locked in here — and it should stay in your pencil case in June.
KEEP YOUR ARCS — THEY CARRY THE MARKS
