In this episode Julie and Phil talk about how builders and engineers use maths and different shapes to make buildings and structures that work! AND maths can help things look nice too!

Here Julie tells us a bit more...

What are the three most basic shapes you can draw on a piece of paper? Go on, have a go!

It's a circle, a triangle and a square. And these three shapes have been used for thousands of years as the basis for building design. The Pyramids were based on triangles; the Colosseum in Rome on a circle and... well most homes are based on squares!

But architects use many more shapes than just these three. The imagination isn't limited to basic shapes like circles, squares and triangles. 

Many human-made artefacts are based on curves. A very common curve in architecture is the parabola - a symmetrical U or N shaped curve, and it's found on bridges.

Julie and Phil mentioned the Golden Gate Bridge.

Symmetry is another important geometric property that’s important for architects. Notice that lots of buildings have shapes repeated such as windows, doors. The shapes that make up a building need to fit together in a pattern.

But what about the builders and interior designers? How do they use geometry? Have a listen to this Maths Matters episode to find out!
