8 Shapes and geometric reasoning

Wherever you look, you will see objects of different shapes and Key words
sizes. Many are natural, but many have been designed by someone.
Make sure you learn and
An architect is a person who plans and designs buildings. Architects understand these key words:
make scale drawings, and often scale models, of the buildings they hypotenuse
plan.They make sure their designs follow local rules and regulations congruent
and they make sure the people who build their buildings follow the corresponding sides
plans correctly. corresponding angles

Towns and cities all over the world have buildings designed to
meet the needs of people who live and work there.
The Burj Khalifa in Dubai is the tallest building in the world
(as of 2012). It is over 828 metres tall and contains 163 floors.
It holds the record for having an elevator with the longest travel
distance in the world. Construction began in September 2004 and
the building was officially opened in January 2010. The Burj Khalifa
cost $1.5 billion to construct.

In the 1970s Piet Blom designed the Cubic Houses, in Rotterdam, the
Netherlands. Each house is a cube, tilted at a 45° angle. Each house
is supposed to represent a tree, with the village forming a ‘forest’.

In this unit you will learn how to interpret and make scale drawings.
You will look at the symmetry of 2D shapes as well as other
properties of quadrilaterals.
