Constructions

Use ruler and compasses to construct triangles, bisectors and loci; draw accurate diagrams

What you'll learn

  1. 1

    Imagine drawing a perfect circle using just a compass — it's like a magic tool! 🎯

  2. 2

    What does a compass need to stay still to draw a circle? 🎯

  3. 3

    Try drawing an equilateral triangle — all sides the same length! 📐

  4. 4

    Let's construct a perpendicular bisector together — it cuts a line exactly in half! ✂️

  5. 5

    Now construct an angle bisector — split an angle into two equal smaller angles! 📐

  6. 6

    A perpendicular bisector does what to a line? 🤔

  7. 7

    An angle bisector splits an angle into how many equal parts? 🎯
