Quadrilaterals, tiling and the eight directions
From “The rhombus” to “Drawing in one stroke”, step by step, each skill with its methods, worked examples and answers.
Skills in this topic, easy to hard
- The rhombusFour equal sides; perimeter = side × 4
- How quadrilaterals are relatedA square is a rectangle and a rhombus
- Cutting up and putting togetherFrom one corner: triangles = sides − 2
- The eight compass pointsStand at the second place and look; reversed, it flips
- Measuring angles in degreesRead the ring that starts at 0°; line 180°, point 360°
- Regular polygons and tilingRegular: equal sides and equal angles. Tiling: the angles make 360°
- Drawing in one strokeOnly 0 or 2 odd points can be drawn in one stroke
