Constructions — O/L Mathematics

Every time a mason marks the corners of a house so the walls meet squarely, or a carpenter cuts a picture frame whose opposite sides match perfectly, they are doing geometry with only two honest tools — a straight edge and a compass. This lesson teaches you that same discipline: how to place points and draw figures exactly where a rule says they must go, without ever measuring with a ruler. It is precise, patient work, and the marks in your O/L paper reward the method as much as the answer.
