Geometry is everywhere Angles, parallel lines, triangles and quadrilaterals can be found all around us, in our homes, on transport, in construction, art and nature This scene from Munich airport in Germany shows the importance of angles, lines and shapes in architecture and design
5 5 angles add to 180 ° (but note that this is not a proof) 5 6 angles add to 360 ° (but, again, note that this is not a proof) Extension Any quadrilateral can be divided into two triangles 5 7 For a polygon with n sides, the sum of the interior angles is 180 2(n −); hence the
