Today and the last previous weeks my group have been planning to build a strong bridge that would span from point A to point B. We've took a long time to build these bridge because we only used toothpicks, ho glue gun and PVA glue. We have learnt so many things about why people build bridges and why they'd used triangles. The reason why people use triangle when bridge building is because a triangle has equal weighted sides and because each side and point is the same measurement.
